Most households have something with tiny button batteries inside. Toys, hearing aids and musical greeting cards are common items powered by button batteries. These batteries can be as small as a centimeter and are a significant hazard. That's especially true for young children who may put them in their mouth, nose or ears.

Button batteries can cause internal burns if ingested or inserted in the nose or ears. When swallowed, these batteries can become lodged in the esophagus, causing a life-threatening medical emergency. Anyone choking or in respiratory distress from swallowing a button battery needs immediate medical assistance. Call 911 right away.
