Every year consumers purchase single-use batteries to power children's toys, smoke and carbon monoxide detectors, remote controls and electronic gadgets. The United States Environmental Protection Agency (EPA) reports that Americans buy close to 3 billion batteries annually. When batteries are improperly disposed of, or incinerated, they release toxic chemicals and heavy metals into the environment. Approximately one in five batteries sold every year is rechargeable. A single set of rechargeable batteries can replace over 100 single-use batteries, says the EPA.
