Automatic tester for batteries

Several primary battery systems are available for diverse applications in electronic instruments, cordless para appliances, flash light, etc. Several specifications are available for testing conventional dry cells differing in test duration, number of discharges and frequency of the tests (onloff) etc. In this paper, an instrument developed in this laboratory for testing several types of primary batteries as per different specifications is described. The instrument can be programmed for different dischange cycles from 1 sec. to 999 hrs. The special feature of the instrument is that it is an ACIDC model with battery under normal float charge and battery fully taking over in the absence of mains supply
