AA-size cells constracted by Battery Technologies Inc. in the U.S. show very good endurance tests. These cells accumulate up to 400 cycles on the 24-Q test and up to 250 cycles on the 10-Q test. The Li-Mn02 cells developed by Sanyo Electric Co. in Japan are termed ML 2430 and ML 2016 with nominal capacity of 70 and 20 mA h, respectively. About 200 cycles are obtained at a capacity of 45 mA h. The flat-type battery ML 2430 with a nominal voltage of 3 V can operate over 3000 cycles at a low discharge capacity of 1 mA h. European efforts are also directed toward Li-Mn02 secondary batteries. Researches are developed by SAFT in France and Varta in Germary (see Table 11.7). 

The specification rechargeable is controversial for many battery experts it requires the possibility of-at least-some hundred to a thousand full cycles to call a system rechargeable. As a compromise, cells designed for 20 to about 200 cycles are designated reusable or renewable (e.g., RENEWAL of Rayovac, USA, for zinc/manganese dioxide, general name RAM of former Battery Technologies Inc. (BTI), Canada).
