As parents, we childproof our homes by covering outlets and locking up cleaning supplies. However, one of the most significant threats to pediatric safety is often hidden in plain sight: the button battery. These small, silver, coin-shaped discs power our remote controls, car key fobs, musical greeting cards, and even some toys.
Because they are small and shiny, children are naturally drawn to them. The CDC notes that a battery lodged in the esophagus can cause serious burns in only 2 hours. If you suspect your child has swallowed one, this is a medical emergency.
Why Button Batteries are a Hidden Household Danger
A button battery (or lithium coin cell) isn’t just a choking hazard. Unlike other small objects, a battery can generate an electric current inside the body.
Why are they more dangerous than other objects?
When a button battery gets stuck in the esophagus (the food pipe), it completes an electrical circuit with the moist tissue of the body. According to the CDC, this can produce an electrical current that creates hydroxide, and medical experts link this to severe injuries and deaths when batteries get stuck in the esophagus.
The battery doesn’t have to be “leaking” to be dangerous. The American Academy of Pediatrics warns that even “dead” batteries can cause serious injury. It adds that the windpipe and large blood vessels can also be damaged.
Red Flags: How to Tell if Your Child Swallowed a Battery
A child may feel fine at first. After a child swallows an object, MedlinePlus lists warning signs that include:
- Difficulty swallowing.
- Excessive drooling.
- Vomiting.
- Chest pain or discomfort.
- Coughing or wheezing.
- Unexplained fever.
The “Silent” Ingestion
The CDC notes that battery ingestions are not always witnessed, which can delay diagnosis and treatment. If you find a device with a missing battery cover or see an empty battery package, treat it as an emergency, even if your child seems perfectly fine.
The 2-Hour Window: Why Every Minute Counts
Time is your biggest enemy when a battery is swallowed. According to the American Academy of Pediatrics, a lithium coin battery stuck in the esophagus can damage or burn through it within two hours.
The CDC notes that the number of serious injuries and fatalities from these batteries has risen as electronics have become more compact and powerful.
Step-by-Step Emergency Actions for Parents
If you suspect your child swallowed a battery, call 911 or go to the nearest Emergency Room immediately.
The Honey Protocol
After calling 911 and while you wait for emergency care, the American Academy of Pediatrics says you can give 2 teaspoons of honey. Your child must be over 12 months old and able to swallow liquids. Give up to 6 doses about 10 minutes apart, and stop if your child vomits. Do not delay emergency care to look for honey.
- Warning: Do not give honey to infants under 1 year old due to the risk of botulism.
What NOT to Do
- Do NOT induce vomiting.
- Do NOT give other food or drink (besides honey, if applicable).
- Do NOT wait for symptoms to appear.
What to Expect at the Emergency Room (ER)
When you arrive, the medical team will prioritize your child. You can expect:
- An X-ray: Typically, an X-ray is taken to see if the battery is lodged in the esophagus.
- Removal: If the battery is in the esophagus, it must be removed immediately via endoscopy (a thin tube with a camera).
- Observation: If the battery has moved into the stomach, it can likely pass on its own. Your doctor may ask you to check the stool until it has passed.
Prevention: Making Your Home a No-Battery Zone
Prevention is the best medicine. The American Academy of Pediatrics recommends steps like these:
- Check the “Tug Test”: Ensure battery compartments on all remotes and toys are secured with screws. If a compartment is broken, tape it shut with heavy-duty duct tape or discard the device.
- Store High: Keep loose batteries in a locked cabinet out of reach and sight.
- Dispose Safely: Wrap old batteries in tape and take them to a recycling center. Even “flat” batteries are dangerous.
Suspect a Button Battery? Don’t Wait: Get Emergency Care Now
If you think your child swallowed a button battery or a battery is missing from a remote, toy, or key fob, treat it as an emergency. Serious internal burns can begin quickly, even if your child looks fine. Head to the nearest emergency room right away for an X-ray and urgent evaluation.

FAQs
Can a button battery pass naturally?
In some cases, if the battery reaches the stomach without getting stuck, it may pass through the stool. However, only a doctor can determine this via X-ray. Never assume it will pass on its own.
How long does it take for a battery to cause damage?
The CDC notes that a battery lodged in the esophagus can cause serious burns in only 2 hours. This is why immediate medical intervention is critical.
What if my child swallowed a battery but isn’t choking?
The American Academy of Pediatrics notes you may not hear any choking or coughing, and the child may feel fine at first. Lack of choking does not mean they are safe.
Are “dead” batteries dangerous?
Yes. The American Academy of Pediatrics says even “dead” batteries can create an electrical current inside the body and cause burns.
Is a coin battery the same as a button battery?
Not exactly. The American Academy of Pediatrics says both are small, round batteries, but lithium coin batteries are thinner and have a higher voltage. The CR2032 is a lithium coin battery.
Can I give my child water?
No. Aside from the honey protocol (for children over 12 months), do not give your child anything to eat or drink.
