Abstract:

Test set, Battery, ANPSM-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-4386PRC-25 was introduced into the military supply system, Test Set Battery ANPSM-13 was used with this battery but with inaccurate results. A program was established to determine the factors that influence the operation of the ANPSM-13 with the magnesium Battery BA-4386PRC-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 ANPRC-77. The upper voltage point indicates that at least 85 of the batterys 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 ANPSM-13 in predicting the capacity remaining in Battery BA-4386PRC-25 are presented. Author
