Final Decision to Certify Hazardous Waste Environmental Technology

Rechargeable Alkaline Household Battery System

Certification No: 98-01-026

Technology Description:

The patented RAYOVAC RENEWAL® Rechargeable Alkaline Household Battery System (Renewal® System) consists of rechargeable alkaline zinc - manganese dioxide dry cell batteries, a charging device/method, and pertinent designer and consumer literature. The Renewal® System was certified as a pollution prevention technology because less alkaline batteries need to be disposed if they can be recharged. Under standard laboratory test conditions, that simulated typical consumer product applications, after 25 charging cycles to specified voltage cutoff points at specified resistance loads, the Renewal® System's batteries supplied hours of service equivalent to seven or more primary alkaline batteries of the same size.

The 1.5 volt batteries are available in standard sizes AAA, AA, C, and D. The charging device is known as a Power Station™. The Power Station™ charger comes in two sizes: PS1 for any combination of AA and AAA batteries, and PS2 for any combination of one to eight AA, AAA, C, and D batteries.

The Renewal® System is appropriate for applications that need high capacity, low self-discharge characteristics, and rechargeability. Rechargeable alkaline batteries are candidates for applications where nonrechargeable alkaline batteries are appropriate. However, rechargeable alkaline batteries such as the Renewal® System batteries are a better choice if the devices are used frequently, use low to medium currents (150 - 400 mA for size AA), and have cutoff voltages of 0.9V or greater. Cutoff voltages lower than 0.9V may allow deep depth of discharge leading to undesirable fade capacity under conditions of very low current and long time of use.
