Fast Facts

  • The number of children visiting emergency rooms after ingesting batteries has more than doubled in the 2010s compared to 1990–2009.

  • Small button or lithium batteries, commonly found in toys and electronics, are a major factor in this increase.

  • Ingested batteries can cause severe injury or death in hours; experts urge keeping them secured and out of children's reach.

A Growing Health Concern

An increasing number of children are ingesting button or lithium batteries and requiring emergency care. Pediatric health experts are urging regulations and education to mitigate this growing issue.

A recent report in the journal Pediatrics revealed that between 2010 and 2019, battery-related ER visits among children doubled compared to the previous two decades. Most affected children are under age 5.

According to Mark Chandler of Safe Kids Worldwide, button batteries are found in many household devices—watches, key fobs, remote controls, flashlights, and toys. Many parents may not realize these items pose a hidden danger.

Why Are Button Batteries So Dangerous?

Batteries are among the most frequently ingested foreign objects by children. Button batteries, due to their small, coin-like shape and shiny appearance, are especially attractive to young children.

Eric Fleegler, MD, a pediatric emergency physician, noted that their small size and non-threatening appearance make them easy to swallow. This increases the risk of ingestion significantly compared to larger batteries.

Severity of Harm

Once ingested, button batteries can cause damage in as little as two hours. If lodged in the esophagus, they can corrode tissue, damage blood vessels, or create holes between the esophagus and trachea, posing life-threatening risks.

Rohit Shenoi, MD, emphasized that the electric current from these batteries can kill surrounding cells and corrode nearby tissue, leading to severe complications.

Signs and Symptoms of Ingestion

Symptoms may be subtle or delayed, making diagnosis difficult without witnessing the ingestion. Children may cough, choke, complain of chest pain, or appear ill. Vomiting and general discomfort may follow as tissue damage begins.

Medical professionals recommend seeking emergency care immediately if ingestion is suspected. The National Battery Ingestion Hotline (800-498-8666) is available for urgent guidance.

An X-ray can confirm the presence of a battery in the body. Prompt diagnosis is critical for safe removal and to minimize damage.

Prevention Tips for Parents

To protect children from battery ingestion, experts recommend the following:

  • Ensure battery compartments are securely fastened in all devices.

  • Store all battery-powered devices out of children's sight and reach.

  • Keep unused batteries in secure locations.

  • Dispose of batteries properly to avoid children finding them in the trash.

Legislation and Safety Regulations

In 2021, President Biden signed Reese’s Law, mandating child-resistant battery compartments in devices. Some manufacturers also use child-proof packaging.

However, older devices and lack of universal compliance still pose risks. Continued industry-wide adoption and parent education are necessary to reduce battery-related injuries.

Final Thoughts

The increasing accessibility of button batteries in everyday items makes this a critical safety issue for families with young children. Awareness, proper storage, and quick response to suspected ingestion can help prevent serious injury or death. As Chandler puts it, preventing ingestion is key, as damage can occur before symptoms even appear.
