• Batteries contain sulfuric acid. To prevent burns, avoid contact with skin, eyes, and clothing. To
prevent fire or explosion keep sparks and open flames away from the battery.

rings, bracelets, and keys. When short-circuited, the battery or conductor may overheat and cause
burns.

household hazardous waste depot for proper disposal. Please refer to “Recycling a Used Battery”, on
