Description:
The EPA's ETV Program, in partnership with recognized testing organizations, objectively and systematically documents the performance of commercial ready technologies. Together, with the full participation of the technology developer, develop plans, conduct tests, collect and analyze data, and report findings.
Rayovac redesigned their alkaline household batteries so that they could be recharged. The additional charge cycles extend battery life by increasing the energy capacity, which benefits the environment by generating less waaste. The design changes included increased void space, an addition of lead and silver. The Rayovac Renewal Rechargeable Alkaline Household Battery System consists of rechargeable alkaline zinc-manganese dioxide 1.5 volt batteries, in sizes AAA, AA, C, and D, and a recharging device for the batteries. Typical consumer applications of household batteries include toys and games, portable audio equipment, cameras, sporting goods equipment, test equipment, personal care products, hearing aids, portable data terminals, sub-notebook computers and personal digital assitants, watches, flaslights, lanterns, and cellular phones. Such applications typically require continuous currents of up to 400 milliamperes (mA), which is withing the range of the Renewal batteries, sized AA, C, and D. Size AAA can supply uo uo 150 mA continuous current, which is sifficient for applications such as clocks.
