ALKALINE BATTERY EVALUATION.
Abstract
This report includes the final results of cycle-life performance tests on 240 12 ampere-hour nickel-cadmium cells in groups of 10 cells and batteries of 20 cells, and 150 20 ampere-hour nickel-cadmium cells in groups of 10 cells. The 12 ampere-hour cells were cycled in four temperature environments with four depths of discharge in each environment while the 20 ampere-hour cells were cycled in five temperature environments with three depths of discharge in each environment. Also included in this report are the results of cycle-life performance tests conducted on 192 25 ampere-hour silver-zinc cells and 192 20 amperehour silver-cadmium cells separated into eight cell groups. Both types of cells were cycled in four temperature environments with three depths of discharge in each environment. The results obtained from the cycle-life performance tests on these four types of cells show that: (1) cell cycle-life with shallow discharges is considerably longer than cycle- life at deep discharges and (2) cyclelife is reduced by high and low ambient temperatures.
