Premier electrosystems offers battery tester. Premier`s battery testers are suitable for testing different types of batteries for their load characteristics. The tester indicates instantaneous battery voltage with the facility to set and read the load current of the battery under test. A digital timer is provided to measure the time duration of the loading test. The moment the battery voltage drops below the low-battery voltage level, the test stops automatically and displays the time taken. The two-minute discharger model comes with a facility to set the time in seconds [about 120 seconds] on 3-digit thumbwheel switches. The battery tester applies the set load for the time duration set on thumbwheel switches and monitors the battery voltage. At the end of the test duration, it latches the last battery-voltage reading. Thus it can be used for pre-dispatch inspection of the batteries.
