Performance characteristics of magnesium--manganese dioxide/nickel--cadmium hybrid system. Technical report
Improvements in the operating characteristics of the 14.4-volt section of Magnesium Battery BA-4386/PRC-25 are obtained by utilizing the battery in parallel directly with nine sealed 250 mAh capacity nickel--cadmium cells in series. Magnesium Battery BA-4386/PRC-25 contains a 3-volt section as well as the 14.4-volt section; however, the 3-volt section was not considered in this experiment. The anticipated power requirements of future field radio sets, which demand up to three times the power of Radio Set AN/PRC-77, the present major military field radio, were used in the study. Delayed action was not observed on any of the evaluations except on the first cycle at 20 F. Improvements in capacity at 70 F ranged from 40% to 98%, based on the BA-4386/PRC-25 alone, with the higher percentage occurring at the higher current drains. At 20 F, 5 hours of operation are obtained with the hybrid sysem, where none is available from the BA-4386/PRC-25 alone. The nickel--cadmium (secondary) battery adds 15% to the total weight of the hybrid system and 11% to the total volume. (GRA)
