Button batteries Information | Mount Sinai

Swallowing batteries

Button batteries are tiny, round batteries. They are commonly used in watches and hearing aids. Children often swallow these batteries or put them up their nose. They can be breathed in more deeply (inhaled) from the nose.

This article is for information only. DO NOT use it to treat or manage an actual poison exposure. If you or someone you are with has an exposure, call the local emergency number (such as 911), or the local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.

Also, you can call the National Button Battery Ingestion Hotline (800-498-8666).

Where Found

These devices use button batteries:

• Calculators
• Cameras
• Hearing aids
• Penlights
• Watches

Symptoms

If a person puts the battery up their nose and breathes it further in, these symptoms may occur:

• Breathing problems
• Cough
• Pneumonia (if the battery goes unnoticed)
• Possible complete blockage of the airway
• Wheezing

A swallowed battery may cause no symptoms at all. But if it becomes stuck in the food pipe (esophagus) or stomach, these symptoms may occur:

• Abdominal pain
• Bloody stools
• Cardiovascular collapse (shock)
• Chest pain
• Drooling
• Nausea or vomiting (possibly bloody)
• Metallic taste in the mouth
• Painful or difficult swallowing

Home Care

Seek medical help right away. Do not make the person throw up unless poison control or a health care provider tells you to.

Before Calling Emergency

Have this information ready:

• Person’s age, weight, and condition
• Time the battery was swallowed
• Size of the swallowed battery

Poison Control

Your local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This national hotline will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

Also, you can call the National Button Battery Ingestion Hotline (800-498-8666).

What to Expect at the Emergency Room

The provider will measure and monitor the person’s vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.

The person may receive:

• X-rays to locate the batteries
• Bronchoscopy — camera placed down the throat into the lungs to remove the battery if it is in the windpipe or lungs
• Direct laryngoscopy — (a procedure to look into the voice box and vocal cords) or surgery right away if the battery was breathed in and is causing a life-threatening airway blockage
• Endoscopy — camera to remove the battery if it was swallowed and is still in the esophagus or stomach
• Fluids by vein (intravenous)
• Medicines to treat symptoms
• Blood and urine tests

If the battery has passed through the stomach into the small intestine, the usual treatment is to do another x-ray in 1 to 2 days to make sure the battery is moving through the intestines.

The battery should continue to be followed with x-rays until it passes in the stool. If nausea, vomiting, fever, or abdominal pain develop, it may mean that the battery has caused a blockage of the intestines. If this happens, surgery may be needed to remove the battery and reverse the blockage.

Outlook (Prognosis)

Most swallowed batteries pass through the stomach and intestines without causing any serious damage.

How well someone does depends on the type of battery they swallowed and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery.

Burns in the esophagus and stomach may result in ulcers and fluid leakage. This can lead to serious infection and possibly surgery. Complications become more likely the longer the battery is in contact with internal structures.

Button Batteries Ingestion – Symptoms and Complications

Health and Safety

​Button batteries are the coin-size batteries found in many electronic devices, like wristwatches, calculators, toys or even recorded birthday cards use button batteries. 

Button batteries are the most harmful type of battery if swallowed by young children, according to the Center for Disease Control (CDC). 

What makes button battery ingestion such a risk for children? The small size of these batteries means they are easy to swallow. They can get stuck in the esophagus (throat), leading to serious injury. They are the leading cause of death by ingestion. Poison control centers across the United States report that about 3,500 button batteries are swallowed each year.

Button Battery Ingestion Symptoms

The symptoms of battery ingestion include:

• Vomiting
• Abdominal pain
• Fever
• Diarrhea
• Difficulty breathing and swallowing

Complications of Button Battery Ingestion

In many cases, the battery passes through the intestines and exits the body safely. However, this is not always the case. They can easily get lodged in the esophagus and lead to dangerous side effects. 

Batteries stuck in the throat cause an electric current and can leak corrosive chemicals, like alkaline electrolyte. These corrosive chemicals can cause internal damage due to the buildup of hydroxide, a chemical that can cause dangerous burns within a couple of hours. Unfortunately, the damage caused may continue long after the battery is removed from the body.

What To Do If a Child Swallows a Button Battery

If your child ingests a battery, take the following steps:

• 
  Immediately call the 24-hour National Battery Ingestion Hotline at 1-(800)-498-8666 or call your poison center at 1-(800)-222-1222.
• Provide the battery identification number, if you have it. It can be found on the package or from a matching battery.
• An x-ray must be obtained right away to be sure that the battery has gone through the esophagus into the stomach. If the battery remains in the esophagus, it must be removed. Most batteries move on to the stomach and can be allowed to pass by themselves.
• Do not induce vomiting.
• Do not allow your child to eat or drink until after the x-ray. If the battery has passed through the esophagus to the stomach, your child may eat or drink.
• Watch for physical symptoms, including fever, abdominal pain, vomiting, or blood in the stools or vomit.
• Check your child’s stools until you know the battery has passed.

How to Prevent Children from Swallowing Batteries

Swallowing batteries is dangerous – no matter the size. Follow these tips to keep your children safe.

• Search your home for devices that may contain button batteries. Do not allow children to play with toys or devices containing these batteries unsupervised.
• Secure button battery-controlled toys and devices out of reach of children.
• Keep loose batteries and replacement batteries securely locked away.

Sophie swallowed a battery when she was two years old. She made a full recovery, but her life was in danger

Two-year-old Sophie Skill from Sheffield, UK had to spend several days in the intensive care unit after swallowing a shiny, round battery the size of a small coin.

Battery acid burned through her esophagus and lung, causing excruciating pain. Her life was in danger.

According to doctors, Sophie’s case is not out of the ordinary: in the UK, on ​​average, two children die each year due to swallowed batteries.

Resembling a button (and a lollipop for a child) button cell batteries are widely used in gadgets and toys, which will soon be in large quantities under Christmas trees, wrapped in gift wrapping.

They can be found in gaming headphones, fitness bands, toy robots, car keys and glowing yo-yos. They are also found in garlands, lanterns, control panels, singing figures, musical cards, and even Christmas sweaters.

Shiny silver button cell is very attractive to the baby. But if a child swallows a battery, the danger is not only that it can choke. The battery can cause severe burns to internal organs.

Claire Skill, Sophie’s mother, hopes that what happened to her daughter will be a lesson to other parents.

Serious injury

Claire still has no idea where Sophie found this ill-fated battery.

“She was breathing normally, but she was screaming very loudly, just sobbing. I’ve never heard anything like that,” says Claire.

She immediately took Sophie to the hospital, and when the doctors found out what was causing her pain, she was immediately sent to the operating room to remove the battery.

A child might mistake a button cell for a lollipop

Although Claire was quick to call for help, Claire was seriously injured.

“In two hours, the battery managed to cause serious damage. They took an x-ray, and it turned out that the button cell burned her esophagus and lung. I had to put her on a ventilator,” she said.

After the operation, the girl spent several days in the intensive care unit and several weeks in the hospital ward.

Sophie is now six years old and fully recovered.

Chemical reaction

Saliva and other bodily fluids cause a chemical reaction when in contact with the battery, which releases corrosive substances, so it is vital in such cases to seek immediate medical attention and do it as soon as possible.

Every minute counts here, experts say. Even a dead battery can seriously harm a child.

Royal Society accident prevention expert Ashley Martin gave some advice:

• Make sure that toys and other devices that use button cells have lockable or screw-on battery compartments batteries a small child can easily open
• Make sure that spare batteries are kept out of the reach of children and that used batteries are disposed of immediately

England’s chief medical officer, Stephen Powys, said: “Young kids can mistake button batteries for candy. We want to educate parents about how deadly batteries can be.”

“The easiest way to protect children is to store batteries out of reach and make sure that used batteries are locked or screwed tightly into their compartments,” he says.

If you suspect that a child has swallowed a battery, do not waste time and seek medical attention immediately.

What should I do if my child swallows a tablet battery?

Many electrical appliances require batteries in the form of batteries. Manufacturers offer devices that differ in electrolyte type, size, shape, and capacity. In the article we will talk about batteries, tablets or coins. You will learn about their features, and what to do if a child has swallowed the device. Read.

Disc batteries features

The tablet battery is a round shaped galvanic battery. For the first time, the device was widely used in electronic watches, so it is also called a watch. Other common names are “tablet”, “coin”, “button”.

There are many types of disc batteries. They differ in size and types of electrolytes. Basic:

• AG0-AG13;
• CR2016;
• CR2025;
• CR.

Due to their small size, batteries can be used in compact devices – watches, toys, sensors, calculators, laser pointers, hearing aids, scales.

How to insert tablet batteries?

When the battery has expired, the tablet battery needs to be replaced. Having bought a similar battery, proceed to remove the old one. First you need to loosen the corresponding clips on the sides of the connector. If the device sits very tightly, then use a screwdriver.

To install a new element into the socket, it is enough to put it on top and press lightly until the characteristic click of the side latches. Then check the fit. The correct position is labeled up.

What should I do if my child has swallowed a tablet battery?

Children aged 8 months to 3 years often swallow foreign objects. Neglect of safety rules sometimes leads to disastrous consequences.

Disc batteries pose a significant risk to children. When swallowed, the battery reacts with saliva and esophageal mucosa to form an alkaline solution. It causes significant damage to the esophagus. The longer the time before device removal, the greater the risk of significant damage to the esophagus.

If a child has swallowed a tablet battery, they should immediately go to the hospital.
