Car Battery Voltage Test. There are two ways to do this. In general, for a car battery with 12 volts, the state of charge is:
With all that extra electrical current from the alternator, a car’s battery usually has a voltage of 13.5 to 14.5 when running. Testing your car battery with a multimeter is a simple and effective way to determine its health.
The Voltage In A Car Battery At Rest Can Range From 0 V To Approximately 12.6 V.
Locate the dc voltage position on the multimeter dial.
The First Thing To Do Is Make Sure You Can Access The Two Terminals On The Top Of The Car Battery.
This test can be performed with a simple voltmeter or multimeter, but a battery tester will determine this as well.
