Abstract
Evaluation tests were conducted on five batteries. Battery, type MS 25211 (AER) is a 12cell, 24-volt, lead acid aircraft storage battery having a rated capacity of 20-ampere-hours at the two hour rate. Four batteries failed to meet the minimum requirements of 100 percent of the rated two hour capacity at the 100th cycle. Three batteries failed on the 61st cycle and one battery on the 63rd cycle. Battery C-1-7E, subjected to the environmental tests, failed before completion of two hours of the required nine hours of vibration. The open circuit voltage dropped from 25.4 to 16.0 volts.
