Abstract : Batteries BA-838( )/U (four pounds) and BA-839( )/U (six pounds) had been designed, fabricated and fully qualified to meet the requirements of one specialized application, the AN/PRC-70 transceiver. This report describes an internal engineering evaluation on these batteries, to further probe the operational characteristics under a wide range of conditions, to determine operational limitations and to establish areas where there is need for further research and development to improve low temperature performance. The present battery designs are most efficient at -40F to power intermittent equipment where the power demands are moderate to high (e.g. AN/PRC-70 and the Army Controlled Air Drop Cargo System (CADCS)). Efficiency is mush reduced with the present designs when low power demands exist, such as for the AN/PRC-25 transceiver. (Author)
