Modified AN/PSM-13 for Field Testing BA-4386/PRC-25.
Abstract
Test set, Battery, AN/PSM-13, using the loaded voltmeter technique, was designed to predict minimum remaining capacity for a number of zinc-carbon batteries. When the magnesium Battery BA-4386/PRC-25 was introduced into the military supply system, Test Set Battery AN/PSM-13 was used with this battery but with inaccurate results. A program was established to determine the factors that influence the operation of the AN/PSM-13 with the magnesium Battery BA-4386/PRC-25 and to design and fabricate a modified version of the tester which would adequately test the battery. Two loaded voltage values were selected to predict the battery state-of-charge relative to its use in Radio Set AN/PRC-77. The upper voltage point indicates that at least 85% of the battery's fresh capacity is remaining; the lower point no less than 15%. A reading between the two points indicates the battery has at least 15% of its capacity remaining; however, it could have up to 100%. The results of the evaluation to determine the accuracy of the modified AN/PSM-13 in predicting the capacity remaining in Battery BA-4386/PRC-25 are presented. (Author)
