Battery voltage drop test method

Test Voltage. Switch your battery tester to voltage testing mode to determine the battery''s state of charge. Most car batteries are called "12-volt," but the actual voltage depends on the state of the charge. This test can be performed with a simple voltmeter or multimeter, but the battery tester will also determine this.

Parasitic Draw Test

A circuit that is not live should have no voltage dropping across it. A small parasitic draw under 1 Amp will take a few days to drain a battery; over 1 Amp could drain a battery overnight. Armed with this information, we can test for a voltage drop across fuses to identify those circuits that are live and causing your vehicle''s battery to drain.
