What are Rechargeable Batteries?

Rechargeable batteries, unlike single-use batteries, are designed to be used over and over again. Recharging allows the batteries to continue to produce electricity and be reused. One rechargeable battery can substitute for hundreds of single-use batteries, so using rechargeable batteries can reduce the amount of waste generated. Some products are designed to use only rechargeable batteries.

More and more Americans are enjoying the convenience of rechargeable batteries. Among the products they are found in are cellular and cordless telephones, video cameras, portable power tools, small appliances, and laptop computers. Approximately 80% of rechargeable batteries are currently composed of nickel (Ni) and cadmium (Cd) and are referred to as "Ni-Cads" (Ni-Cds).

According to the Environmental Protection Agency, nickel-cadmium batteries pose no real risks while the battery is in use. However, the environmental release of cadmium can be of concern when the batteries are discarded with ordinary municipal waste. Cadmium can accumulate in the environment by leaching into groundwater and surface water from landfills, and it can enter the atmosphere through incinerator smokestack emissions. Cadmium has been associated with numerous human illnesses, particularly lung and kidney damage.

Recycling programs can prevent these adverse effects of disposal by diverting batteries from the municipal waste stream. In 1995, the battery industry set up the Rechargeable Battery Recycling Corporation (RBRC) to administer the collection and recycling of rechargeable batteries. RBRC collects used Ni-Cds and sends them to the International Metals Reclamation Company (INMETCO) in Ellwood City, Pennsylvania, for recycling. Individual households can take advantage of the program by bringing their used batteries to household hazardous waste collection centers or participating retailers.
