Hermetically sealed Ni-Cd cells were cycled with and without stabistor charge control. The capacity range used was 5 to 20 ampere-hours. In the four charge control circuits BCC-9, BCC-10, BCC-11 and BCC-12, the stabistors were effective in clamping cell voltages and minimizing gassing. In BCC-11, 20 AH Ni-Cd cells were cycled and the stabistors were effective in preventing internal cell shorting and extending battery life. Some antireversal studies were also conducted. Initial results indicate that antireversal diodes are partially successful in preventing gassing during cell reversal. The data suggest the use of a larger antireversal diode for adequate protection.
