Bacterial Vaginosis (BV): Overview and More

Bacterial vaginosis (BV) is a common but frustrating condition in which the normal balance of the vaginal flora is disrupted, leading to an overgrowth of anaerobic bacteria. Symptoms include itchiness, vaginal discharge, and an unpleasant odor. While BV is readily treated with antibiotics, the recurrence of infection is common, usually within 12 months of treatment. BV tends to affect women in their childbearing years and is often associated with douching, unprotected sex, multiple sex partners, and other risk factors.

Bacterial Vaginosis Symptoms

Of the 21 million American women believed to be affected by bacterial vaginosis each year, only around three million actually experience symptoms. When they occur, BV symptoms tend to mild but persistent and may include:

A grayish white or yellow vaginal discharge
A “fishy” smell that can get worse after intercourse
A burning sensation when urinating
Vaginal itchiness, redness, and swelling
Vaginal bleeding after intercourse

Less commonly, a BV infection may lead to urination problems, pain during sex, and the development of pelvic inflammatory disease (PID).

While BV symptoms are rarely serious, they can undermine the integrity of vaginal tissues and increase your vulnerability to sexually transmitted diseases (STDs) such as gonorrhea, chlamydia, trichomoniasis, and HIV.

Moreover, if an infection occurs during pregnancy, you may run an increased risk of preterm birth, low birth weight, and, in rare instances, a second-trimester miscarriage.

Causes

Bacterial vaginosis is not considered an STD because the infection is not caused by a foreign pathogen like HIV or syphilis. Instead, BV occurs when healthy bacteria in the vagina are depleted, allowing unhealthy ones to predominate and cause infection. Gardnerella vaginalis is one of the most common of these “bad” bacterias, but others can cause infection, too.

This imbalance can be caused by changes in the vaginal acidity or problems with the immune response, both of which decrease the body’s ability to control the bacterial overgrowth. Sex can often instigate an infection by introducing new or excessive microbes into the vagina.

Some of the more common causes of BV include:

Unprotected oral, vaginal, or anal sex
Multiple sex partners
New sex partners
Shared sex toys
Douching
Smoking
Intrauterine devices (IUDs)

Genetics are also believed to play a part, either by promoting inflammation or by causing lower-than-expected levels of protective Lactobacilli in the vagina.

Diagnosis

Since bacterial vaginosis is not caused by a single agent, a diagnosis would be made based on an evaluation of your symptoms and your various lab test results. This would generally involve:

A review of medical history
A pelvic exam
A pH test to check for vaginal acidity
A microscopic evaluation of your vaginal secretions

The microscopic exam would either look for “clue cells” (vaginal cells studded with bacteria) or use a gram stain to help differentiate the bacterial types and measure the proportion of “good” bacteria to “bad” ones. Based on a review of criteria, a doctor can either confirm the diagnosis or perform other tests to ensure that it’s not some other illness (such as a yeast infection or genital herpes).

Home-based tests are also available but tend to be far less accurate.

Treatment

The standard treatment for bacterial vaginosis is a short course of antibiotic drugs . The types used in first-line therapy, called metronidazole and clindamycin, are highly effective in treating BV and have relatively mild side effects.

The preferred first-line regimens include:

Metronidazole 500 milligrams taken by mouth twice daily for seven days
Metronidazole 0.75 percent vaginal gel applied once daily for five days
Clindamycin 2.0 percent vaginal cream applied at bedtime for seven days

Alternative options include a clindamycin vaginal suppository or tinidazole tablets. Despite the efficacy of treatment, recurrence is common and may require additional or even multiple treatments to achieve control.

Common side effects include nausea, stomachache, cough, sore throat, runny nose, and a metallic taste in the mouth.

In addition to prescription antibiotics, there are a number of home and supportive remedies that may help. They include probiotics (found in nutritional supplements and foods like yogurt) which may help prevent recurrence, and boric acid, an old-time remedy experiencing a resurgence in medical interest.

Prevention

As common as bacterial vaginosis is, there are things you can do to reduce your risk. They include safer sex practices to avoid exposure to harmful bacteria and practicing good vaginal hygiene to reduce your odds of infection.

To prevent bacterial vaginosis:

Limit your number of sex partners.
Use protection for oral, vaginal, or anal sex, including condoms and dental dams.
Do not douche.
Wipe from front to back after urinating.
Avoid IUDs if you have recurrent BV or a past severe infection.

A Word From Verywell

Even with the best prevention efforts, bacterial vaginosis can sometimes occur. Try not to stress out. Instead, seek treatment and make every effort to avoid exacerbating the condition.

If the symptoms are driving you to distraction, make your life easier by ditching the tight pants and wearing looser clothing or a skirt. To treat an itch, apply a cold cloth directly to the vagina or splash with cold water in the shower. Scratching will only make things worse.

Finally, if you are being treated with antibiotics, do not stop halfway through even if your symptoms disappear. Doing so can increase the risk of antibiotic resistance and make treatment all the more difficult if the infection does, in fact, return.

9 Kinds of Vaginal Discharge: Colors, Consistencies and More

Gray discharge can also be a sign of trichomoniasis, which is an STD which can be treated and cured with antibiotics. It’s very important to see your doctor at the first sign of gray discharge.

Note: if you’ve never had a period before, gray discharge can actually be a sign that your body is getting ready to start menstruating. “It’s a warning that you’re going to get your period in the next 6 months,” Dr. Hersh explains. “When you look under the microscope, what you see are mature vaginal cells that are sloughing off. It’s really just the lining of the vagina ramping up and the cells are going from immature to mature.”

Dr. Hersh notes that sometimes girls and their moms assume it’s a yeast infection and treat it with over-the-counter medicine, which can just cause more irritation. “The best way to address it is with water to keep the area as clean as you can and add a protective barrier like A&D ointment or coconut oil — something to protect the vulva, but nothing medicated,” Dr. Hersh recommends.

4. Dark Brown, Red, or Pink Vaginal Discharge

Discharge with a red, dark brown or pink tint is usually just a sign that your period is about to begin. It can also be the result of light bleeding (mixed with normal discharge) after penetration.

5. Green or Yellow Vaginal Discharge

“If your discharge is foamy, itchy, yellow, or yellow-green in color, it can be a sign of an STD or other infection,” Cullins says. “A doctor or nurse can do exams to figure out whether your yellow discharge is caused by an infection or not,” Cullins says.

6. Foul-Smelling Vaginal Discharge with Pain

“Pelvic inflammatory disease (PID) is an advanced infection of the uterus, fallopian tubes, inside of the abdomen, and sometimes, ovaries. It can be accompanied by abdominal pain, pain during pelvic exam, pain during sex, and fever,” Cullins says. “It’s usually caused by untreated chlamydia or gonorrhea, but it can be caused by other infections as well. Sometimes PID causes bad-smelling vaginal discharge, but sometimes PID doesn’t cause any noticeable changes in your discharge, so if you have pain symptoms, don’t wait to see a doctor or nurse.”

7. Creamy Vaginal Discharge

This could be a sign that you might be pregnant. “During pregnancy most women have more and thicker discharge. Many women’s discharge becomes creamier in consistency,” Cullins says. “Vaginal infections can occur during pregnancy, so if something about your discharge doesn’t seem right, tell your prenatal care provider. They can figure out if what’s going on is normal or a possible problem.”

8. Heavy Vaginal Discharge

If it just seems like you have more vaginal discharge than usual, it may be due to your menstrual cycle. “It’s normal for the amount of vaginal discharge you have to vary from day to day, depending on where you are in your monthly cycle,” Cullins says. “Some days it might seem like you don’t have any, while other days your underwear might be wet with discharge all day. Other days you’ll be somewhere in between.”

9. Slippery, Clear Vaginal Discharge

This kind of discharge is usually a sign you’re turned on. “If you’re aroused, discharge tends to be more slippery and clear.” Cullins says. The clear fluid is called transudate, and it seeps through your vagina walls as blood flow increases to the area. Transudate makes sex comfortable and helps get sperm to eggs.

What to Do If You’re Concerned About Vaginal Discharge

If your discharge is out of the ordinary (cottage cheese-like, yellow, green, gray, or foul-smelling) or is accompanied by pain or vaginal itching, don’t hesitate to make an appointment with a gynecologist who can diagnose the issue and guide your treatment plan. “Stress and certain medications can cause changes in your vaginal discharge. If your discharge changes drastically or is accompanied by vaginal pain, bleeding during sex, or pain when you pee, talk to a doctor or nurse so they can make sure everything’s okay. “

If you do feel like something is wrong based on your discharge, do not douche. “Don’t douche or use over-the-counter cleansers inside your vagina” Dr. Cullins says. “Douching messes with your vagina’s natural cleaning system and isn’t a treatment for vaginal infections. In fact, douching can actually make certain infections worse.”

Is it normal to have a lot of discharge with a strong smell?

I’m around the age 16 and 17. I’m not sexually active, I have had sex once, but even before I had sex I’ve always had a discharge problem, it happens randomly and it’s so embarrassing! It gets all over my underwear, it’s white ish, clear, but it does have an small to it, not fishy, nor is it a disgusting smell but it’s a smell. A strong smell. I try so hard for no one to notice. And when I started birth control it kinda slowed down not as much but my mom just toke me off it and it’s happening again. Is something wrong with me? Should I go get check out?

You can relax. What you just described doesn’t sound like a discharge problem at all. It’s normal and healthy to have clear or white discharge (that may be slightly yellow when it dries) that has a certain smell, even a strong smell. Some days you may have more of it than others.

The time to worry about your discharge is if it starts to have a bad, fishy kind of odor, or if the color or texture changes a lot. Yellow or green discharge can be a sign of an infection, like an STD or bacterial vaginosis, and very thick white discharge could mean you have a yeast infection.

Don’t worry too much about other people noticing the way your vulva smells. Generally other people won’t be able to smell it at all unless they get very close to your vulva, like when you’re having sex, and in that case most people like the way their partners’ vulvas smell.

If you feel really uncomfortable when you have a lot of discharge, try using panty liners to keep it from staining your underwear. But since you liked being on birth control and you’ve had sex before, you might want to try talking to your mom about starting it up again. Check out some tips for talking to your parents about sex and birth control questions.

What it can tell you about your health

Though we may not readily admit it, we all analyze the contents of our underwear when we’re sitting on the toilet or before we toss it in the laundry. Turns out, this habit that many may label as “gross” or “weird” is neither of these things. In fact, medical experts encourage it.

“The goal is always to feel confident about your vaginal health,” says Dr. Sara Zarè, a Naturopathic Doctor (ND) at Radiant Health in San Francisco, California. “Many women are uninformed when it comes to what should be going on down there. By knowing what your vaginal discharge should look and smell like, you could spot a nasty infection.”

In addition to keeping infections at bay, paying attention to discharge can offer clues into your cycle and fertility. “A woman can often note an increase in vaginal discharge, as well as cervical mucus, during ovulation, pregnancy, times of sexual arousal, and just prior to the menstrual period,” adds Stefani Davis, a Women’s Health Nurse Practitioner (WHNP) and Doctor of Nursing (DNP) who works at a high-risk clinic in Fort Wayne, Indiana. “Vaginal discharge can be a helpful indicator of both fertility and cycle tracking.”

So before you divert your eyes from the sticky stuff in your panties, keep in mind that your vaginal discharge is actually a tool that can help you better understand your health. (In other words, scrutinize away!) We collaborated with three experts to create this vaginal discharge guide to support you on all of your future underwear investigations.

What exactly is vaginal discharge?

First, it’s important to remember that vaginal discharge is common for women of reproductive age. “Vaginal discharge is a normal occurence that all women experience throughout their lifetime,” says Davis. “It’s a fluid that’s composed of the secretions that are released by the cervical mucosa as well as the oils secreted by the glands near our vaginas.” Essentially, vaginal discharge is primarily made up two components: Fluid released from your cervix and oils released from your vaginal glands.

So why do I have it?

“The purpose of vaginal discharge is to maintain the moisture and health of the vaginal tissues,” says Dr. Amanda Barrett, an OB-GYN at Nashville’s Women Obstetrics & Gynecology. Ever experienced vaginal dryness or chafing? (Spoiler alert: It’s not comfortable.) As Barrett points out, this is one of the benefits of vaginal discharge—it keeps the vagina moist.

In terms of vaginal health, Zarè explains that discharge helps the vagina clean and rid itself of infection. “Vaginal discharge keeps the vagina clean by removing dead cells and bacteria, which helps to prevent infection,” she says. “Thanks to vaginal discharge, there is no need to use cleaning products like douches, soaps, or shampoos in this area. The vagina is excellent at self-cleaning.”

This is because vaginal discharge contains “lactobacillus,” a healthy bacteria and microorganism that naturally exists in the vagina and its discharge. Lactobacillus is responsible for fighting any “bad,” infection-causing bacteria. Davis says, “The normal organisms in the vagina that are present in vaginal discharge, such as the lactobacillus species, help prevent against vaginal infections.”

How do I know if my discharge is normal?

When talking with all three experts, they used four attributes to describe vaginal discharge as it relates to your health, cycle, and fertility: smell, texture, color, and volume. (Who knew sommeliers and women’s health specialists relied on the same criteria?) According to Davis, healthy discharge is usually clear to white with a thin texture. “Women have their own unique smell to vaginal discharge, but normal discharge does not have a foul-smelling odor.”

Zarè adds that like smell, volume differs between patients. “The amount of discharge varies from woman to woman.” All three experts emphasized that both the consistency and volume of healthy discharge can shift depending on where you are in your cycle.

Speaking of discharge and your cycle…

Dr. Barrett breaks this down for us: “During menstruation, it is bloody and may be red, pink, brown or nearly black. After menstruation, the amount of discharge will be less, but there is often sticky, thick, and white discharge. A few days before ovulation, when a woman is most fertile, the discharge becomes stretchy, creamy, and wet. This ‘egg white cervical mucus’ is more hospitable to sperm. During ovulation, the discharge then becomes thin, stretchy and very slippery. After ovulation, the discharge is stretchy, creamy, and wet, similar to how it appeared prior to ovulation.”

However, Davis points out that many external variables such as medications, hormonal changes, sexual practices, and anatomy can impact discharge. When using it to track your cycle or the days you’re most fertile, she advises to look at the whole picture, which can also include discharge. “It’s important to monitor other changes throughout your cycle, reliably detect when ovulation has occurred, and correctly track your menstrual cycles,” she says. “There are many helpful applications and technologies out there to aid women in tracking their menstrual cycles and fertility, as well as education from their healthcare providers.”

What about not-so-normal discharge?

If vaginal discharge ever takes on an unusual smell or color and is accompanied by burning or itching, it’s critical to make an appointment with your doctor. This could indicate an infection or other condition. Davis and Zarè provided the following examples using the texture, volume, smell, and color criteria.

A large, frothy amount of green or yellow-colored and offensive-smelling discharge is consistent with trichomoniasis, a common and treatable sexually transmitted disease (STD).
Yellow or green-colored mucopurulent (resembling mucus or pus) discharge can indicate chlamydia or gonorrhea, two types of treatable STDs.
Brown or brownish discharge can be a sign of an irregular cycle or in less frequent cases, endometrial or cervical cancer. (Keep in mind, it’s normal to have brown, red, pink, or nearly black discharge during your cycle.)
A moderate amount of white, curd or cottage cheese-like discharge is consistent with candida, commonly known as a yeast infection. This is caused by excess yeast growing in the vagina.
Thin and watery white or gray discharge that has a fishy odor can be a sign of bacterial vaginosis, which occurs when there’s more harmful than beneficial bacteria in the vagina.

There’s a reason we rely on practitioners like Barrett, Zarè, and Davis: It’s often difficult for us to self-diagnose infections based on symptoms like discharge. “Talk with your healthcare provider if you notice potential signs of an infection so that you can receive the proper treatment,” advises Davis.

In terms of treatment, there are many over-the-counter options for yeast infections. However, bacterial infections like bacterial vaginosis require a medical diagnosis and prescription, as well as STDs. “With bacterial infections, an antibiotic is the first line of treatment,” says Davis. “Most importantly, it is imperative to see a medical professional if you are concerned you may have been exposed to an STD. If left untreated, STDs can cause complications in the future.”

Get down with your discharge

All three women agree on the importance of establishing familiarity with your discharge. By doing this, you’ll be able to notice if something is ever unusual and make a doctor’s appointment if necessary. “It is very important to know what is normal for you and see a doctor if you notice any major changes,” says Zarè.

Doctor’s orders: On your next trip to the bathroom, take a peek at your underwear to familiarize yourself with your vaginal discharge and your health.

Let’s Just Chill Out And Start Talking About Vaginal Discharge, OK? OK.

If you were to pull, at random, a pair of worn underwear from the hamper of pretty much any biologically female person in the world, you would probably find a flat, dried streak of white or yellowish discharge around the crotch. This is not because women’s underwear is “dirty” or because vaginas are “disgusting” or because the stuff that comes out of them is “gross.” It’s because vaginal discharge is normal.

And now it’s time for everyone to get over it.

Mic/Getty Images

On last week’s episode of the UK’s Celebrity Big Brother, one of the contestants, actress Stephanie Davis, was shamed for leaving a pair of her worn underwear on top of a pile of other clothes that needed to be washed. One of Davis’s housemates, John Partridge, proceeded to pick up the offending undies and parade them around the house for the others, claiming it looked like the person who wore them left “pigeon shit” behind.

“We need to name and shame now,” Partridge said. “This can no longer go on.”

He wasn’t the only one to bully her; the other housemates joined in, prompting Davis to tell them she’s been “having problems down there” (while also noting, aptly, that it’s not actually any of their business). But then the media piled on as well, with one outlet describing the incident as one of the “most disgusting” and “vile” moments in the history of the show. Unfortunately for them, discharge is a part of life.

Of course, it’s not a part of life we talk about often. When we do, we typically end up talking about the feelings of shame associated with them, or asking questions about what is and is not normal. On Reddit, there are dozens of threads by women about their vaginal discharge, from questions about how much is “normal” to how to clean it off of underwear.

But there’s a reason people laugh so openly at the jokes people like Amy Schumer and Jenny Slate make about the reality of discharge: It’s, um, the fact that discharge is a reality.

“Vaginal discharge is normal,” Dr. Pratima Gupta, an OBGYN and fellow at Physicians for Reproductive Health, told Mic. “It’s not gross. It’s just part of normal physiology. There are glands in your vagina, just like there are saliva glands in your mouth; discharge is just fluid made in the glands in the vagina.”

According to Gupta, the point of discharge is to keep vaginas lubricated and to keep the tissue soft, so that the walls of the reproductive organ don’t rub up against each other, which would cause friction, scratchiness and discomfort. The fluid can also help regulate the level of bacteria inside of the vagina and cervix, and plays an important role in keeping everything clean and free of infection.

There’s no way to quantify how much discharge is “normal,” Gupta added, as it varies from woman to woman; even for an individual woman, the amount of discharge she produces can vary with her menstrual cycle. “It’s going to come out and be on their underwear,” she said.

“It’s not gross. It’s just part of normal physiology.”

And yet, virtually any time something other than a baby comes out of someone’s vagina, it’s considered nasty. (Think for a moment of that line in Lil Wayne’s “A Milli,” where the rapper refers to himself as “a venereal disease/like a menstrual bleed.”) As Laura Bates pointed out at International Business Times, treating discharge and other vaginal fluids, including menstrual blood, as if they are shameful or grotesque perpetuates stigma:

The truth is that shaming these completely normal bodily functions is just another tired, sexist double standard. We consider a sweaty, active man to be the peak of virile attractiveness, but a sweating woman to be worthy of a scathing headline… These might seem like minor examples, but the stigmatization of vulvas and vaginas has a cumulative and insidious impact, from the rapidly increasing number of young women having their labia surgically altered, to the millions of girls around the world who miss out on education because of menstrual taboos.

Such taboos devalue the sort of typical, basic female physiological functions that allow our species to survive. They also make women believe that their bodies are embarrassing and wrong when in reality they’re working just as they’re supposed to. Maybe the reason everyone freaks out so much about a stain in a woman’s underwear is because it forces us to confront the most horrifying fact of all: she’s a living, breathing human being.

Your Guide to Cervical Fluid

Next you may notice sticky fluid, called that because it might feel tacky between your fingertips. Sometimes it feels springy or is flaky too, but its distinguishing feature is it won’t feel wet. It may look like white or yellow streaks in your underwear and might leave a crust.

Then for a few days, you may see creamy or milky cervical fluid. It’s usually white, opaque, and wetter than the sticky stuff you saw before.

Fluid resembling raw egg white usually comes after that. Like raw egg white, it’s clear and slippery. You may feel like your vagina is lubricated. Have you ever felt like you started your period then gone to the bathroom and just seen fluid? It’s probably this type. If you pinch some of the fluid between your thumb and pointer finger and then open them, it can stretch an inch or more. Because of its high water content, it may look like a circle of fluid in your underwear.

After that the fluid will usually get progressively stickier and dryer, until bleeding begins again. You may experience a watery day the day before you menstruate, which is probably the lining of your uterus beginning to break up.

So if you see any of the above types, know that these are all perfectly normal. Certain types of fluid can be signs of infection: Potential red flags include gray, green, or cottage-cheese-like mucus that smells bad to you. These signs could be reasons to contact your health care provider, especially when combined with itchiness, irritation, and/or swelling.

OK, Got it—But Why’s It There?When sperm are released into the vagina, they swim through cervical fluid before they reach the cervix and beyond. Cervical fluid is like a bouncer; depending on the type of cervical fluid present, sperm will be able to pass through the fluid or not.

Remember the egg white fluid? While the presence of any cervical fluid can indicate a fertile time, egg white fluid is considered a particularly strong indicator of fertility, because it’s usually present around the time of ovulation, when an egg is released. And, it’s sperm’s BFF: It protects and nourishes, and is pH-matched to, sperm. Under a microscope, it looks like tons of tiny ferns, providing passageways that sperm can move through and filtering out irregular swimmers.

In this friendly fluid, sperm can stay alive for up to five days, hanging out at the cervix, waiting to see if an egg is released. If ovulation occurs, then they’ll bid adieu to the cervix and race to fertilize an egg in the fallopian tubes. Cervical fluid is just as critical to fertility as sperm, y’all! Without it, our acidic vaginas could kill sperm on contact.

Even if a potential pregnancy isn’t on your radar, these fluid changes are still relevant. They’re a sign of hormonal health, because our fluid responds to the incredible hormonal dance between estrogen and progesterone. And if we’re aware of the characteristics of our normal cervical fluid, then we’re better able to recognize any abnormalities. Knowledge is power, and greater understanding of our bodies can lead to greater self-love.

90,000 How do I properly charge my iPhone with a new battery?

When buying a new phone, especially if it is an iPhone, users are often worried and strive to follow any instructions as closely as possible in order to extend the life of their gadget. A common question that interests many is the correct charging of the device. Let’s figure it out.

How to properly charge a new phone?

First, connect your iPhone to the charger and plug in to the mains.
The first charging of the device takes some time and is at least 12 hours.
When the gadget reaches 100% charge, you need to completely discharge the battery, and after that you can recharge the smartphone. Such actions allow you to “stretch” the battery to its maximum capacity. It is possible to achieve a complete discharge of the battery by using it in the usual way. You can make this process faster by watching videos, actively using the Internet via Wi-Fi, playing “heavy” games, etc.

How to prolong battery life?

Apple recommends that you follow some tips to keep your battery stable.

It is worth regularly updating the software, because often updates have new energy-saving technologies.
Do not expose gadgets to sudden temperature changes, and this applies not only to phones, but also to tablets and laptops. A suitable temperature regime is considered to be 16-22 degrees. If the temperature is more than 35 ^to, the battery may be damaged. Cold conditions directly affect the autonomous operation of the device and temporarily reduce its duration.
When charging equipment, it is better to remove the covers.This way the device will not overheat.
If due to some reasons you will not use the device for a long time, it is better to leave the gadget half charged. A complete discharge of the battery may result in the battery not charging at all in the future. The storage temperature of the apparatus should be below 32 degrees.
iPhones have some ways to extend their battery life. One of the options is to turn on automatic brightness control, so that the gadget takes into account the lighting and adjusts.The second option is not to turn off Wi-Fi, because this access method requires less power consumption.
iOS 9 has been equipped with a new power saving mode. In this mode, we have set the function of notifying the user that the battery charge is very low. Plus, it saves energy by disabling iCloud sync and AirDrop data transfer. Calls, sending SMS and using the Internet remain. This mode turns off by itself while charging the device.
Apple developers report that the operating system iOS 9 is one of the most efficient, because it allows you to find out the most energy-consuming applications.The user can independently turn off the activity of such programs in the background.

The car battery is discharged what to do. Complete discharge of the car battery.

At first glance, an absurd question. But only at first glance. If the battery is no longer as strong as it was immediately after purchase, it can be given a “second wind” by successively discharging and then fully recharging. Such a procedure is even desirable, it should be carried out before the cold season.

Let’s say right away: “discharging the battery” does not mean subjecting it to a deep discharge.
Going below these values, and excess electrons will break the chemical bond and release lithium, which will bind with oxygen to create lithium oxide, and the battery will swell again! If you keep using a bloated battery, it will only get worse and your best bet is to get rid of it. Slight inflation is a sure sign that your battery is dying and should be used with caution.Once the battery cools down, it will deflate and usually people will continue to use it, but keeping it up to date is very important.

That is, turning on all on-board systems with the engine off, and waiting for the battery to give up all the energy is a dead matter. A calcium battery will not survive such a procedure at all, batteries of other classes will also not treat it very well. It is necessary to discharge to clearly defined electrical indicators. Namely: 10.3 V on the battery as a whole and 1.7 V on each bank.We repeat: the procedure is suitable only for low-antimony batteries, it is better to limit other classes of batteries to a normal charge. On the other hand, the accumulators of the “lead-antimony” system, after such a reboot, can work as in their younger years.

Ideally dispose of it, because you risk fire if the cell bursts, so you are warned! There are so many variables that determine your battery’s life cycle, and if it is abused it will only last for a few loads, but if handled correctly, you can get just over 200 charges.It depends on your application and capacity requirements …

Battery Disposal

For obvious safety reasons, it is best to completely discharge batteries outdoors before discarding them. One of the best solutions is to discharge slowly to completely empty them with a lamp or bulb. If the battery is physically damaged, discharge can be dangerous and you must be careful before disposing of it. Search the internet and you will find different methods to get rid of it. Hope you learned and you get the best out of your batteries.This post will be updated based on your feedback and my findings in this area.

To begin with, how to discharge?

There are several options, but all require a multimeter, voltmeter or charger with clamping the voltage at the terminals. We connect the equipment to the connected battery and “cut in” the high and low beam. You do not need to connect all the electronics on board – the battery does not like both fast charging and fast discharge. So, we are waiting for the coveted figures.After that, we remove the battery and charge it. If you are not close to the car, we remove the battery and perform all the manipulations at home. The best discharge option is to connect a 12 V, 60 W light bulb to the battery. These are installed in the headlights of the car. We will just get the required 5 A of consumption. At the same time, you can calculate the real capacity of your battery. If a light bulb is not at hand, any 5-7 A consumer will do.

Next – charging.

You need to start it immediately. If it is not possible to immediately charge the battery, do not even start the discharge procedure – destroy the battery. In a discharged “zero” battery literally in a couple of hours the process of sulfation begins – coating the plates with lead sulfate. The deeper the sulfation, the less likely the battery will work at all. So, right after discharge – charging. It is desirable with small currents. If you’re not going anywhere in the coming days, perfect.Put the charger on a current of 1.5 to 5 A and wait for the full filling of the container. At 1.5 A, charging can take 2-3 days (depending on the battery capacity), but the charge with low currents partially desulfates the battery, and therefore returns its capacity.

The residual energy measurement will be more accurate. This calibration operation must be performed monthly. The lack of communication between a compatible battery and a PC results in a whimsical measurement. Only original batteries have a specific indication of the actual capacity during playback.

Remove the battery, repeat the charging procedure. Battery life is highly dependent on the configuration used, the applications loaded, the battery management configuration, and the functionality used. As with all batteries, their maximum capacity will decrease over time with use.

Up to two such KTC cycles can be performed at a time. But even one may be enough for the battery to recover and serve you faithfully for another couple of years.

Hello, Kostya.

Car storage battery (AKB) loses its performance during discharge. However, after a deep discharge, it not only loses its performance, but in this case a rapid and, unfortunately, irreversible degradation of the equipment occurs. The car owner must remember this and make timely and correct charging. However, it is not uncommon for a car battery to be completely discharged.This can happen, for example, due to a poorly tensioned alternator belt, faults in the electrical wiring, a door that is not tightly closed, headlights turned on while parked, etc. Such a battery needs a recovery charge. Below are tips that can be used if the batteries are not too worn out and sulfated (they can also be restored, but this requires special equipment and professional skills).

Two maneuvers that save battery life.If not used for a long time, the lithium-ion battery should be stored at 50% capacity. The Netherlands already has hundreds of charging stations for electric vehicles, and this number is constantly growing. It takes a lot of energy to charge an electric vehicle. More than charging a scooter or electric bike. Electric vehicle requirements range from 20 to 50 kWh. Therefore, these charging points are not suitable for charging electric vehicles. Often on the terminal itself it is indicated for which type of electric vehicle it is adapted.

How to determine the degree of discharging of the battery?

You can determine the degree of discharge of the battery by measuring the density of the electrolyte. In a battery that is 100% charged, the density is 1.27 g / cm3. A density of 0.01 g / cm3 corresponds to 6% charge. You can also estimate the battery discharge by the voltage at its terminals. So, at 100% it will be 12.8 V, at 50% – 12.2 V, at 25% – 12.0 V. If the voltage at the terminals is less than 11.8 V, then such a battery is completely discharged.

Can a regular socket charge cars?

Most EVs can be charged at 230 V, i.That is, the voltage available at a standard outlet. However, it is advised to check if other “greedy” appliances are connected at the same time as the car, as this requires a lot of current to recharge: 16 amps. For example, if your washing machine, microwave, and car are connected to the same area at the same time, it could lead to overload.

However, some manufacturers have not designed their vehicle to be rechargeable from a regular outlet.In this case, your car will be charged using a special charging protocol and a special connector that is not a regular electrical outlet. For these situations, at home or at your workplace, the installation of wall-mounted electrical boxes will be provided. This type of installation will be performed by a qualified technician.

Charging methods

To charge a fully discharged battery, use conventional chargers. As a rule, there are two charging methods – with constant current or constant voltage.Other methods (stepwise, impulse, reversible, combined, etc.) are implemented on specialized professional equipment. Each of these methods has its own advantages and disadvantages, so you need to consider what equipment is available.

How long does it take to charge my electric car at my workplace?

First, we can calculate the recharge time using the formula. Once you know this data, you need to apply this formula.Obviously the same calculation can be applied to a 32A terminal and then will give you 22kW of power. Note that the first reboot 80% is faster than the last 20%. Your battery will recharge – 1 hour after 80% charge.

How long does it take to charge my electric vehicle?

When it comes to recharging the battery in your home, it depends on several factors. When you know this data, you just need to apply this formula.Make sure the charger is connected to a fuse separate from the main unit. Your battery will be recharging – 3 hours after reaching 80% charge.

Like green electric car

This applies when the battery is charged at least 50%. Even if electricity is generated in a coal-fired power plant, the environmental benefit remains with the electric vehicle.

Rule for charging a discharged battery

When charging a fully discharged battery, it is important to observe the following rule.During normal charging, which is regulated in the technical documentation of the battery manufacturer, the charging current is determined based on the battery capacity, and it should be 10% of the capacity. In this case, a completely discharged battery must be charged within 15 hours. For example, if your battery has a capacity of 70 Ah, then the charging current should be 7.0 A. You can use a lower current with a longer charging time. In the case of a 70 Ah battery, it is better to charge it with a current of 3.5 A throughout the day.This advice applies mainly to classic batteries with lead-antimony plates. Modified models that use silver and calcium alloying or a hybrid design can be charged with a higher current first.

Are batteries recyclable?

It should also be noted that electric vehicles do not discharge harmful gases and particles into the air. Electric car batteries can, of course, be recycled like lead-acid batteries in conventional cars.Increased demand and high prices for raw materials used in batteries are prompting companies to recycle lithium-ion batteries. For example, they can be used to store energy in homes, in cogeneration plants, or, for example, to store peak energy for windmills. The fact that multiple applications can be found in these recyclable batteries helps to reduce the negative impact on the environment.

In chargers that do not provide for current regulation, it decreases with charging.Therefore, it is necessary to determine the initial charging current from the technical documentation of the equipment and find out if it is suitable for your battery.

Naturally, it is better to use modern devices for charging. They can not only provide an optimal charging mode, but they also turn off automatically after the battery is fully charged.

How much does it cost to drive an electric car?

It should be noted that electric vehicles are exempt from tax treatment.It should also be noted that companies can receive subsidies for the use and installation of public charging stations. Some municipalities are even considering new additional measures, such as free parking for electric vehicle owners.

It should be noted that an electric car contains far fewer mechanical parts subject to wear and tear than a conventional car. This leads to a reduction in the number of interviews and a decrease in the cost of interviews. Tests should be done with respect to the frequency at which the battery is to be tested and maintained.

Best regards, Sergey.

90,000 What parameters of batteries should be checked and how to do it?

When using batteries in any facility, especially in uninterruptible power systems, their condition must be monitored and checked regularly. In this material, we will consider the main parameters of the battery, and also consider what devices and how you can control and test them!

The main task when checking the condition of any storage battery is to find out whether it has sufficient capacity, whether it can provide the characteristics declared by the manufacturer for the required time.However, only a few basic parameters are determined directly by means of measurement – voltage, current. In serviced batteries, you can also measure the density of the electrolyte. Measurements can be carried out repeatedly, recording the change in values over time. All other parameters and characteristics are not measured directly, but are derived according to the method developed by the manufacturer, and it depends on the type of battery, and on the manufacturer’s recommendations, and on the type of load connected. It should be borne in mind that many dependencies that characterize the operation of the battery are non-linear.Other factors can also affect, for example, the influence of temperature.

When performing short-term measurements using even the most advanced methods, testing is not accurate quantitative, but qualitative in nature. The only reliable way to measure the battery capacity is to completely discharge it for many hours with careful fixing of the parameters during the entire process. But it is not always possible to use such a long procedure in practice, especially if there are a lot of batteries.Nevertheless, short-term evaluative measurements are enough to distinguish an efficient battery from a worn-out one that has lost its capacity, and to replace the battery in time.

Battery test methods

1. Load connection

A working or secondary load of one size or another is connected to the battery for a while. The voltage drop is measured with a voltmeter or multimeter. If the procedure is performed several times, a certain time is waited between measurements for the battery to recover.The data obtained is compared with the parameters declared by the battery manufacturer for a given type of battery and a given load.

2. Measurements with a load fork

The structure of the simplest load fork is shown in the diagram:

The device is equipped with a voltmeter, in parallel with which a large power load resistor is installed, and has two probes. In older models, voltmeters are analog; newer models are usually equipped with an LCD display and a digital voltmeter.There are load plugs with a complicated circuit, using several load coils (replaceable resistances), designed for different voltage measurement ranges, designed for testing acid or alkaline batteries. There are even plugs used to test individual battery banks. In addition to a voltmeter, advanced devices may include an ammeter.

The data obtained during measurements must also be compared with the parameters declared by the manufacturers for a given type of battery and a given resistance.

3. Measurements using special devices, testers, battery analyzers

Cutlery Pendant

A fundamental development of the idea of a load plug can be considered a family of digital testers Kulon (Kulon-12 / 6f, Kulon-12m, Kulon-12n and others) for checking the condition of lead acid batteries, as well as other similar devices. They allow you to quickly measure voltage, approximately determine the capacity of the battery without a control discharge and store several hundred, and sometimes thousands of measurements in memory.

Kulon devices are powered by a battery used for measurements. The included wires with alligator connectors have parts isolated from each other, which provides a four-clamp connection to the battery and eliminates the influence on the readings of the resistance at the points of connection of the clamps. According to the developer, the device analyzes the battery response to a test signal of a special shape, while the measured parameter is approximately proportional to the active surface area of the battery plates and, thus, characterizes its capacity.In fact, the accuracy of the readings depends on the validity of the manufacturer’s methodology.

Battery capacity – the electrical charge given off by a fully charged battery – is measured in ampere-hours and is the product of the discharge current and time. To accurately determine the capacity, it is necessary to discharge the battery (a long process, many hours), constantly fixing the amount of charge given by the battery. In this case, the relative capacity of the battery varies nonlinearly with time.For example, for a rechargeable battery type LCL-12V33AP, the relative capacity changes over time as follows:

Discharge time, hours	Relative capacity,%
0.1	37
1.3	48
0.7	53
1.9	76
4.2	84
9.2	92
20	100

The Kulon device by means of a quick measurement approximately determines the capacity of a fully charged battery .It is not intended to assess the state of charge of the battery, all measurements must be carried out on a fully charged battery. The device transmits a test signal for a short time, registers the response from the battery and after a few seconds gives the approximate capacity of the battery in ampere-hours. At the same time, the measured voltage is displayed on the screen. The obtained values can be stored in the memory of the device.

The manufacturer emphasizes that the device is not a precision meter, but allows you to estimate the capacity of a lead acid battery, especially if the user calibrated the device himself using a battery of the same type as the tested one, but with a known capacity.The calibration procedure is detailed in the instrument manual.

Testers PITE

Another type of battery testing device is PITE testers: model Kongter BT-3915 for measuring the internal resistance of batteries.

Control is carried out using a color touch screen, but the main control buttons are located on the keyboard in the lower part of the case. The device can test batteries with a capacity of 5 to 6000 Ah, with 1 battery cells.2 V, 2 V, 6 V and 12 V. Voltage measurement range – from 0.000 V to 16 V, resistance – from 0.00 to 100 mΩ. The device allows you to set the type of batteries to be tested, to measure voltage and resistance (model 3915) or voltage and conductivity (model 3918), and on their basis judge whether the battery capacity corresponds to the one declared by the manufacturer or not. The Capacity parameter is displayed as a percentage.

The instrument interface allows both single measurements and sequential measurements (up to 254 measurements in each sequence, the total number of results is more than 3000), which is convenient when checking a large number of batteries of the same type (in the latter case, the results are saved automatically, in addition to the data, the ordinal measurement number).Depending on the settings, the device can use its own criteria or values specified by the user to give a result (status Good, Pass, Warning or Failed). Test results via the USB port can be transferred to a computer for viewing and subsequent reporting.

Fluke

Analyzers

A deeper development of the same idea – the Fluke Battery Analyzer 500 series (BT 510, BT 520, BT 521), which measure and store in memory voltage, internal resistance of a stationary battery, temperature of the negative terminal, voltage during discharge.With the availability of additional accessories, you can measure and save in memory, and other parameters. Tests can be carried out both in single measurement mode and in sequential mode; using custom profiles. It is possible to set threshold values for various parameters. The built-in USB port allows the collected records (up to 999 records of each type) to be transferred to a computer for reporting using the included Analyze Software.

The probes of the device have a special design: an internal spring-loaded contact is intended for measuring current, an external one for measuring voltage.When you push down on the stylus, the inner tip moves inward so that both contacts of each stylus touch the surface at the same time. As a result, the same probes allow you to organize both 2-wire and 4-wire connection to the battery poles (the latter is necessary for measuring Kelvin).

The device allows you to measure the following parameters:
Internal resistance of the battery (measurement takes less than 3 s).
Battery voltage (performed simultaneously with internal resistance measurement)
Temperature of the negative terminal (an IR sensor is provided on the BTL21 Interactive Test Probe next to the black tip)
Discharge voltage (determined several times during discharge or during load test)

It is also possible to measure ripple voltage, measure AC and DC current (with a current clamp and adapter), perform the functions of a multimeter.With Fluke analyzers, you can use the BTL21 Interactive Test Probe with a built-in temperature probe. A wide variety of additional accessories are compatible with the devices (current clamps, extension cords of different sizes, removable flashlight, etc.).

Although the device has a rich functionality, the key step in determining the state of the battery remains the comparison of the measured values with the calculated or specified by the manufacturer for this particular type of battery.The Fluke Battery Analyzer 500 Series is handy for mass inspection of battery health. The sequential mode and system of profiles allow you to perform the necessary measurements one after another, the results are memorized by the device and stored in an orderly form, sequentially numbered and divided into groups. But the device does not have the function of directly or indirectly measuring the battery capacity in ampere-hours – if only because it is hardly possible today for batteries of different types to develop a single accurate method for such a determination.

All of the devices listed above, although different in size, belong to the portable class. A separate group can be divided into stationary complexes for testing batteries, which can conduct quick tests with the determination of internal resistance, control all parameters, including the active and reactive components of resistance, control the discharge / charge process, etc. Such complexes are more likely addressed to research laboratories, industrial battery manufacturers and new equipment developers than end users.

4. Full discharge / charge

Today, full discharge and charge is the only direct and most reliable way to determine the battery capacity. Specialized devices for monitoring the discharge / charge of the battery (UKRZ) allow deep discharge and subsequent full charge of the battery with constant monitoring of the capacity. However, this procedure takes a very long time: 15-17-20-24 hours, sometimes more than a day, depending on the capacity and current state of the battery.Although the method gives the most accurate results, its application is limited due to the time required.

5. Measurement of electrolyte density

In serviced batteries, to determine their condition, it is possible to measure the electrolyte density, since there is a direct relationship between this parameter and the battery capacity. The density of the electrolyte can change due to various reasons, which are also interrelated (frequent deep discharge of the battery, sulfation, suboptimal density of the electrolyte, evaporation and leakage of the solution, etc.).etc.). The battery starts to discharge faster and gives less charge. It should be understood that the density of the electrolyte, even in a serviceable battery that is in perfect condition, is not a constant, it changes with the temperature and state of charge of the battery. Moreover, for different regions, the recommended electrolyte gravity differs depending on the typical climatic conditions.

The density measurement with the hydrometer can be compared with the following diagram for acid batteries.

Depending on whether the density of the electrolyte is greater or less than the required one (and deviation in both directions is harmful for the battery), you can partially or completely replace the electrolyte, pour distilled water or a solution of the required concentration, making sure to ensure stirring. As with all the previously described methods of checking the condition of the battery, the key is to compare the measured values with the recommendations of the battery manufacturer and follow all the prescribed maintenance procedures.

Conclusions

Each method of determining the current state of the battery has its own advantages and disadvantages. Which one to use depends on your tasks and capabilities. This pivot table will help you navigate.

Method for determining the state of the battery	Benefits	Disadvantages
Load connection	Sufficiently realistic results without the use of specialized equipment	Time required for multiple measurements Measured parameters are manually documented
Load plug, dedicated analyzers and testers	Device portability Ease of use Fast measurements, especially multiple measurements Some models are capable of taking measurements without removing the battery from operation Specialized models allow you to save the results and transfer them to a computer for preparing reports	Part of the battery parameters is determined by indirect methods Estimated measurement accuracy
Full discharge / charge	The only reliable way to estimate battery capacity	A very long procedure – many hours, sometimes a day
Electrolyte density measurement ρ	Direct determination of the battery condition by electrolyte concentration	This method applies only to serviced batteries

Samsung Galaxy – How to properly charge your battery

Modern smartphones are used not only for making calls and sending SMS. Gadgets like the Samsung Galaxy are not just a phone, but a whole multimedia center in your pocket. High-quality camera, maps with GPS-navigator, various browsers for surfing the world wide web, applications for communication and work and, of course, games.

This set of functionalities, combined with a large screen, naturally requires a fairly large amount of electricity. Therefore, the battery is a very important part of any smartphone and Samsung Galaxy gadgets are no exception.

Despite the fact that there are no clear rules for the use of batteries, following a few simple guidelines will help extend the “life” of your smartphone battery.

Reasons for reduced battery life

In order to keep your Samsung smartphone battery healthy for a long time, there are two main reasons to keep in mind that significantly reduce battery life:

Temperature.Continuous overheating of the battery is guaranteed to lead to a loss of 30-35 percent of its capacity within one year. Do not expose your smartphone to an excessively long charging process, as excessive voltage causes the battery to gradually heat up.
Fully charged or discharged. Your Samsung Galaxy smartphone battery will last better and last longer if you don’t charge it to 100 percent, so take it out of charge when it reaches 80 to 90 percent. Leaving your phone connected to a charger when the battery is fully charged can reduce battery life by 40% in a year.It is often not recommended to allow complete discharge. The ideal battery condition is 40 to 85 percent.

Following a few simple rules will extend the battery life of Samsung Galaxy from 300-500 to 1200-1500 full charge / discharge cycles:

Do not charge your smartphone for an excessively long time (do not leave it plugged in overnight).
Do not charge to 100%.
Avoid frequent full discharge.
Do not overheat the battery.
Use only original chargers.

How to properly use your new Samsung Galaxy

battery

There is an opinion that a new battery should be brought to full discharge several times, and then charged to 100%. These statements are only true for the older type of nickel-cadmium batteries. In modern smartphones, lithium-ion (Li-Ion) power sources are used that do not have a “memory effect” and other disadvantages.

With regard to Li-Ion batteries, research shows that extremes will wear them out rather than extend their lifespan.This means that every time you allow a full discharge or charge of the gadget, you reduce its resource.

Does the “fast charge” mode harm the battery

The development of technology in the field of power supplies lags far behind the growth rate of the functionality of smartphones in general. The more advanced Samsung Galaxy requires more power than its predecessors. Unable to integrate high-capacity batteries into the gadget, many manufacturers offer a “quick charge” function, with which you can quickly recharge your phone up to 70%.

It is worth noting that the first versions of fast charging technologies did have a negative impact on battery performance. This was primarily caused by overheating, which gradually reduced the capacity of the power supply.

Modern versions of the technology are more adapted and practically do not affect the lifespan of the Samsung Galaxy smartphone. If your gadget does not overheat, you can freely use this function without worrying about battery performance.

Samsung Galaxy Wireless Charger – Can You Use

New Samsung Galaxy smartphones support wireless charging using induction method. This method is very convenient and does not require any power cables to be connected to the device. You can use wireless charging, with one condition – to prevent the battery from overheating. If you begin to notice that your gadget is very hot, you should refuse such charging or use it for a short time.

Resume

Now you know, in order to extend the life of your Samsung Galaxy battery up to 1300-1500 discharge / charge cycles, you should avoid overheating and stick to 40-80 percent battery charge rates.

This does not mean that it is necessary to constantly observe these rules. After all, it is not always possible to check the battery readings and not everywhere there is access to the charger. Maybe you are going on a trip and, in that case, it makes sense to fully charge the battery.You should stick to these guidelines whenever possible, and you are guaranteed to extend the life of your battery two to three times.

90,000 iPhone does not show charging level. What to do if iPhone shuts down even before

battery is completely discharged

From time to time, iPhone users are faced with the problem of spontaneous shutdown of the smartphone before the battery is completely discharged. There may be several reasons for this problem, and today we will try to consider ways to solve this problem.

Fully discharged to 0% and fully charged iPhone.

Sometimes the premature shutdown problem is related to the battery indicator of the device. If you suspect that the charge indicator is showing the wrong value, then first you need to completely discharge the smartphone, and then charge it to the maximum. If the problem was in the wrong display of the charge, then it should disappear.

Backup and restore.

Factory reset essentially makes your iPhone what it was when you bought it from a software perspective.But before that, in order not to lose all data on the device, you need to make a backup copy. For this you need:

1. Launch iTunes and connect your iPhone to your computer.

2. In the application, in the list of connected devices, select your smartphone and click on the “Create a copy now” button.

3. After completing the process, click the “Restore iPhone” button.

4. Restore data on a smartphone from a backup.

If we talk about this process, then it completely erases everything from the device’s memory, restores iOS and automatically patches the system to the latest version.This allows you to install all the necessary updates and bug fixes. In the event that the problem with disconnecting the device had a software reason, restoring the iPhone should certainly help.

If none of the above helps, then the last option remains.

Contacting the service center.

The final cause of a premature shutdown could be a hardware problem with the device battery itself. If the software methods did not help, then you need to contact the service center.There, the smartphone will pass all the necessary tests.

To begin with, I myself am an engineer, but without a specialized education, nevertheless, I am quite familiar with the operation of batteries and even worked for 5 years on very powerful and large electrolyzers. I will not say that I am an electronics guru, but the stupidity of the phrase “battery calibration” has always been completely obvious to me, but only faced with this problem I realized that I was just looking at this problem and its solution, as a person who understands the battery device, but I did not take into account the programmatic component of the question.

I will describe the problem that I encountered. The iPhone battery began to drain quickly, and it began to do so extremely inadequately. For example, the phone could be discharged and turned off in a matter of hours, but after a short rest, I could use it. At the same time, the battery charge indicator signaled me about 30%. Also, very often the phone was discharged and turned off at the moment when the battery charge was 50%, the same charge remained when connected to the charger, I could even disconnect the iPhone from the network at that moment and calmly continue to spend this unfortunate 50%.

And even observing the blatant behavior of the battery, I would justify it or the wear and tear of harsh operation, if not for the warm weather and infrequent use of the phone. That is why I started to figure out what exactly is “battery calibration” on the iPhone and iPad.

Materials on the topic:

How to Calibrate iPhone and iPad Battery

Many people know that a rechargeable battery inevitably loses capacity with daily use, and also that when you see a charge indicator with a value of 1%, the battery is not completely discharged.A special controller is responsible for the limits of charge and discharge, with which, as it turns out, problems may arise over time. As a result, you may face the fact that your iPhone or iPad will not fully charge, or, conversely, turn off uncharged, as it happened with me.

And so, what are we going to do:

Fully drain the iPhone, iPad battery;
we charge up to 100%, preferably through an outlet, since the charging speed will be higher. Leave the device on charge for another 40-50 minutes;
disconnect from the charger and completely re-set the battery from 100% to 0%, without connecting the device to a computer (iTunes) or charging;
We again fully charge the iPhone, iPad to 100%, leaving it connected to the charger for 40-50 minutes and cut it again.That is, we repeat the second and third points.

Basically, that’s all. With enough free time, I recommend repeating the second and third paragraphs a third time.

Despite the primitiveness of all the above actions, my problem of turning off the iPhone without charging has been solved. If you encounter a similar problem, try it, it is highly likely that the instructions presented above will help you. The main thing is to fully charge and fully discharge, otherwise you are unlikely to achieve a positive result.

I note that on the network some users unsubscribe that this instruction helped them also to extend the battery life of the iPhone, iPad.

Some buyers are susceptible to the belief that purchasing smartphones from Apple, they will forever be relieved of the need for frequent recharging and other problems with battery performance.However, such statements are a common myth invented by fans of the line. Apple’s gadgets, as well as phones from other manufacturers, can guarantee high-quality battery performance only for the first time after purchase. With longer use, the battery life of the device is noticeably reduced, and this is not surprising. In fact, the answer to the question: “Why is the iPhone battery running out of power?” lies in the peculiarities of the battery itself, in the specifics of operation or in the device settings set by the user.

To understand what caused the rapid consumption of the smartphone’s energy reserve, first you need to check if any long-term applications are running on the smartphone. See if you have Wi Fi or Bluetooth enabled, automatic search for updates, geolocation, or regular self-checking of your mailbox. In fact, there are a huge number of applications that can constantly drain battery power without manifesting themselves in any way.Finding them and disabling them can significantly increase the autonomous operation of the device without any outside intervention.

Another factor that may cause battery malfunctions is a violation of the operating recommendations of the smartphone. The battery is very sensitive to various external factors, and this must also be taken into account. For example, a decrease in charge may result from the device getting wet or overheated. Also, the balance of power can be disturbed due to the use of external chargers or interruptions in the operation of the power grid.Also, mobile batteries do not react well to sudden changes in temperature.

Well, the simplest explanation is the usual aging of the battery – that’s why the battery charge on the iPhone jumps. Initially, any lithium-ion battery is designed for a certain number of charging cycles, and the more actively you use the capabilities of your mobile phone, the sooner the permissible resource will be exhausted. That is, the charge accumulator may stop working normally simply because its time has expired, and in this case, no repair is able to restore its operability, since the lithium storage rooms fail gradually, but irrevocably.

In iPhones, the average battery life of a standard battery is 700-1000 cycles. In some cases, if a number of recommendations are followed, the battery life can be slightly extended, but sooner or later problems will still appear. And when the gadget is no longer able to hold a charge, it is necessary to replace the battery with a completely new one. However, only a specialist can carry out a high-quality reinstallation, therefore, when the time comes, be sure to contact mobile workshops for help.

Hello everyone! The iPhone has a lithium-ion battery, and these batteries are not known to have a memory effect. Then why calibrate them at all? The fact is that the battery capacity drops over time () and if you have had your phone for a long time, then in the absence of battery calibration, strange things begin … provide information about the battery charge level. As a result, various non-standard situations begin to occur: an unexpected shutdown by 20-30%, freezing of the charging indicator (long display of one value), incorrect data is shown about how charged the iPhone is, etc.

By the way, although in this article I write about the iPhone everywhere, this method of battery calibration is great for other Apple equipment – iPad and iPod.

Let’s summarize the signs that clearly indicate that it is time to calibrate the iPhone battery:

iPhone shuts down when there is still charge percentage. It would seem that he still has to work and work, but he bam and turned off.
In some cases, calibration will help those users who run out of batteries very quickly.True, this is just one of the smartphone methods.
If the iPhone freezes for a long time at one percent of the charge, and then the indicator sharply “jumps” by several tens of percent.
It is advisable to perform calibration every 2-3 months for absolutely all iPhone and iPad users. If you’ve never done it, now is the time!

At least one of the described cases is your situation? Then read on and learn how to properly calibrate your iPhone battery!

5 easy steps:

Wait until the device is completely discharged.Precisely completely and completely (absolutely, “zero”, so that it is not included at all).
We put on charge (preferably from the network) and do not touch it (of course, you can answer an urgent call, but you do not need to play and use). We wait until it is charged to 100%.
We leave connected for another hour or two. What for? For reliability! After all, the iPhone shows us incorrectly charging? Not properly! So, you can’t trust him. And despite the fact that the screen displays 100% charge, the battery may not be fully charged! Therefore, to be sure, after reaching 100%, do not turn off the plug from the outlet immediately, but wait at least another hour.
Disconnect from the network and do a hard reboot. To do this, press and hold two keys – Home and Power on, until the apple icon lights up on the screen.
We use the device until it is completely discharged.
We repeat this procedure 2-3 times.

Important! When you start doing the second loop, you do not need to recharge your iPhone for a short time! The circuit should be exactly like this – from 100% to 0%, only then to charge, charge, hard reset and discharge to 0% without recharging.

Many users began to have a problem with charging iPhone and iPad. Not only did mobile devices begin to discharge faster, but also the charge indicator itself seemed to go berserk, starting without any reason to “jump” from one indicator to another. We figured out the problem situation and found a solution.

This manual is the answer to the user’s request in our. You can also describe your problem in it – we will consider it as soon as possible and offer a solution.

The solution to the bouncing battery indicator is to restore the device and set it as new. This method helped many users to get rid of not only an unpleasant error, but also to normalize the autonomous operation of the device.

Important: Restoring the device and configuring it as new means deleting all data and settings. Before restoring data using iCloud or iTunes.

Step 1.Connect your iPhone, iPad or iPod touch to your computer using a USB cable and launch iTunes. If iTunes is not installed on your computer, you can download the latest version of the program on the official Apple website.

Step 2. Select the device in iTunes.

Step 3. On the Overview tab
“click the button” Restore [device]
“. To start recovery, function “ Find iPhone
”must be turned off.

Step 4. Create a backup by selecting the item of the same name in the window that opens.

Step 5. Confirm the start of the restoration and wait for the process to finish.

Step 6. On the device registration page, select “ Configure as new
“and click” Continue
“.

Done! Now you need to perform the initial setup of your iPhone, iPad or iPod touch (on the device itself) and check if the problem with the “jumping” charge indicator is fixed.

There are many myths about the properties and use of gel and AGM batteries. Nevertheless, these are just more modern modifications of liquid lead-acid batteries, and what is known about ordinary car batteries applies to a greater extent to their gel and AGM counterparts.

Of course, there are differences, but they are associated with different acid densities and with different types of lead plate separators. In addition, in most car batteries, the lead plates are much thinner and therefore lighter.

Below we provide answers to frequently asked questions about this topic:

What is a full discharge or zero discharge?

A full discharge is an uncontrolled discharge of the battery to a voltage of 0 (zero) Volt .

A discharge to zero leads to irreversible sulfation and a significant loss of capacity in any lead-acid battery, regardless of its type.In most cases, at zero discharge, a complete irreversible loss of capacity occurs and all that remains is to dispose of or sell such a battery to lead buyers.

A situation often leads to a full discharge when, during a long absence of normal operation, they forget to turn off everything that is connected to the positive terminal of the battery. As a result of the lack of periodic recharging from the mains, generator or solar panels, even a small current from the equipment connected to the battery leads to an uncontrolled voltage drop below the critical value of 10.5 Volts.

With regard to solar power plants, this situation can arise if you leave the charge controller connected for the winter, and the solar panels are covered with snow. This will lead to the fact that in the absence of recharging from solar panels, the controller’s own consumption will slowly lead to a complete discharge of the battery.

To prevent such a situation, before leaving the solar power plant in the country for the winter, it is recommended to wait until the battery is fully charged, then disconnect the SB from the controller and disconnect the controller and everything else from the positive terminal of the battery.

What is a deep discharge battery and what is the difference between 100% discharge and zero discharge?

Deep discharge batteries can be called any gel or AGM batteries, since they provide an average of 200 to 400 discharge cycles at 100%.

Moreover, the greater the mass of the battery with the same capacity, the more lead it contains and the more number of cycles it can work. Therefore, when choosing a battery for deep discharge purposes (for electric forklifts, electric wheelchairs, children’s electric vehicles, boat electric motors, solar power plants), it is recommended to buy the model with the largest mass.

A 100% discharge (deep discharge) is a battery discharge to a voltage of 10.5 Volts , and not to zero Volts.

Is it harmful to short-circuit a gel battery?

In a short circuit, gel batteries are capable of delivering very high currents (from hundreds to thousands of Amperes, depending on their capacity).

The very fact of a short circuit is not harmful to the gel battery and does not affect the service life.However, short circuits should be avoided as at the same time, a huge amount of energy is released in the external jumper that caused the short circuit, the jumper heats up to hundreds of degrees and can cause a fire.

To comply with fire safety rules, it is recommended to install a DC circuit breaker or a fuse link as close as possible to the battery terminal block, and protect the terminal with a rubber cap.

How to properly store a gel battery and when does sulfation start?

Any lead-acid battery, regardless of its type , should be stored in a fully charged state at temperatures from -20 to +50 degrees (optimally at +20).

After several months of storage, the voltage may drop due to self-discharge. When the voltage drops below 12.6 volts, sulfation of the lead plates begins, which can lead to a decrease in battery capacity.

During storage, it is recommended to check the voltage of the battery every six months and not to allow the voltage to drop below 12.6 Volts, and when this level is reached, recharge the battery from a charger or using solar panels.Following this recommendation will significantly extend the life of the lead-acid battery.

After long-term storage of the battery, it is necessary to carry out an equalizing charge in order to equalize the voltages on the battery banks. The equalization voltage for all Delta series batteries is 2.4 Volts per two-volt cell or 14.4 Volts for a 12-volt battery. For other brands of batteries, check the voltage of the equalizing charge with the manufacturer.

How to check the gel battery when purchasing?

First of all, you should check the voltage:

If it is in the range from 12.8 to 13.0 Volts, then this means that the battery is new and no more than 6 months have passed since its release.You can safely buy it.
If the voltage at the terminals is in the range from 12.6 to 12.8 Volts, then you should think about it, because obviously it has been stored for more than half a year.
If the voltage is below 12.6 Volts, then such a battery is definitely not worth purchasing, because it may have a loss of capacity due to long-term storage without recharging.

In addition to checking the voltage with a voltmeter, if possible, check the voltage under load using a load plug, which gives a current close to the battery capacity.

When checking a serviceable battery, the readings of the load plug should be in the range of 11.5-12.0 Volts, depending on the load current and battery capacity.

Do I need to charge the battery before using it?

Despite the fact that rechargeable batteries are sold in a charged state, it is recommended to recharge each battery separately, using an equalizing charge, before using it.This is especially important if the batteries will be connected in series for connection to a 24 or 48 volt system.

It is recommended to measure the voltage on each battery once every six months. If a voltage difference of more than 0.1-0.2 Volts is detected, it is necessary to perform an equalizing charge and, if necessary, balance the battery using a 12 Volt charger, carrying out an equalizing charge of each battery separately.

When operating the battery in an autonomous power supply system, it is recommended to do from 2 to 4 equalization charge cycles per year (preferably at least once every 6 months).
