Industrial Battery Capacity Tester works on an input voltage supply of 230V AC with a frequency of 50Hz and can test up to 10 battery packs at a time. The Tester has discharge current that is settable using 10 turn helical potentiometers with counters and ensures maximum current which can be set up from a range of 10ma to 2000ma. The Tester is equipped with a four digits timer that indicates time in minutes when a push switch corresponding to a battery that is pressed and the time remains recorded as long as the power is ON. Industrial Battery Capacity Tester continues the discharge until the battery terminal voltage is dropped to the set limit per cell after which the discharge will automatically stop.
