Abstract : A long life, high energy density, zinc-silver oxide battery, capable of high power output, was developed to meet the demand for a lightweight high power source for use with Radar Set AN/PPS-5. Batteries capable of one year activated shelf stand and one one-hundred (plus) life cycles are now attainable. These batteries are shipped in the unactivated state and are supplied with premeasured amounts of electrolyte in sealed plastic containers. Before use, they are filled and charged. The BB-622/A was improved in two generations and the improved battery evaluated over a range of conditions to establish capacity, cycle life and environmental qualities. This evaluation was conducted by simulating the Radar Set AN/PPS-5 requirements. Comparative test data of the original battery and the improved BB-622/A show a threefold increase in cycle life at room temperature and a twofold gain at 113F for the improved battery. The present BB-622B/U in a monoblock structure results in a battery of approximately thirty percent greater capacity in the same volume. Cost data on a per cycle basis and watthour basis are presented for the commercial product and the improved BB-622B/U. (Author)
