Button Batteries - National Safety Council

Tiny Batteries Pose Sizeable Risks

The number of serious injuries or deaths as a result of button batteries has increased nine-fold in the last decade.

Children want to explore. And young children have a tendency to put most of what they find laying around the house in their mouths.

Every parent knows this, but what parents don't always know are the hidden dangers lurking inside seemingly harmless items, such as remote control devices and keyless remote door openers for vehicles. What's inside? Coin lithium batteries. You may know them as button batteries. These little silver-colored batteries power everything from toys and electronics to watches and musical greeting cards.

Button Batteries can be Extremely Dangerous

If swallowed or placed in the nose or ears, button batteries can cause serious injury or death, according to the National Capital Poison Center. More than 3,500 people of all ages swallow button batteries every year in the United States. Most pass through the body and are eliminated, but sometimes they get hung up in the esophagus. An electrical current can form in the body and hydroxide, an alkaline chemical, can cause tissue burns that can be fatal.

Fourteen fatalities involving children ranging in age from 7 months to 3 years were recorded from 1995-2010, all from the ingestion of button batteries, according to the Centers for Disease Control and Prevention. This has led the Consumer Product Safety Commission to call for the electronics industry and battery manufacturers to develop warnings and industry safety standards.

Emmett's Story

Karla and Michael Rauch of Phoenix, through the non-profit foundation Emmett's Fight, are sharing their story to educate families, parents, caregivers and grandparents about the dangers of button battery ingestion.

Their son, Emmett, removed a button battery from a DVD player remote control device and swallowed it in October 2010. The battery burned two holes in his esophagus and was lodged one centimeter from his heart. He has undergone countless surgeries in a courageous battle to live a normal life.

In 2014, doctors reconstructed his airway, enabling him to work on his speech in preparation for kindergarten, and he had his tracheostomy removed, clearing a path for him to play soccer.

"As a mother, I replay the morning we noticed Emmett's illness over and over in my mind," Karla writes in a Cincinnati Children's blog. "How did I not know?"

Lessons Learned

In partnership with Safe Kids Worldwide and Energizer, Karla and Michael Rauch share what they've learned in hopes others steer clear of disaster. Both say parents can take steps to protect their children:

  • Look in your home for any items that may contain coin-sized button batteries
  • Whenever possible, select batteries in child-resistant safety packaging
  • Keep loose or spare batteries locked away
  • Place devices out of sight and out of reach of small children
  • Be mindful of toys belonging to older children in the home that might contain button batteries
  • Share this life-saving information with caregivers, friends, family members and sitters

What to Do in an Emergency

The Poison Center outlines steps to take if you suspect someone has ingested a button battery:

  • Call the 24-hour National Battery Ingestion Hotline (800) 498-8666
  • If available, provide the battery identification number, found on the package or from a matching battery
  • In most cases, an X-ray must be obtained to determine whether the battery has passed through the esophagus into the stomach; if the battery remains in the esophagus, it must be removed immediately
  • Don't induce vomiting; don't eat or drink until the X-ray shows the battery is beyond the esophagus
  • Report fever, abdominal pain, vomiting or blood in stools immediately

Button batteries also can cause permanent injury when placed in the nose or the ears, the Poison Center says. Young children and elderly people (wearing hearing aids) have been particularly involved in this type of incident. If you suspect a battery lodged in the nose or ear, watch for pain or discharge, and do not use nose or ear drops until the person has been examined by a doctor.

By the Numbers

Safe Kids reports these hard facts surrounding button battery ingestion:

  • Every year, more than 2,800 kids are treated in emergency rooms after swallowing button batteries; that's one child every three hours
  • The number of serious injuries or deaths caused by button batteries has increased nine-fold in the last decade
