Charged Battery, How Many Volts Should Battery Have?
Fully charged auto battery should measure 12.6 volts or more. With the engine is running, this measure should be 13.7 to 14.7 volts. With a multimeter to show the voltage of the battery, a simple test of the electrical system by starting the car and turn on the headlights. If dim, that indicates the lights are running off the battery and that little or no charge is being produced by the alternator. If the lights get brighter as you rev the engine, it means the alternator is producing some current, but may not be producing enough at idle to keep the battery properly charged. If the lights have normal brightness and don’t change intensity as the engine is revved, your charging system is probably functioning ok. If experiencing problems with your battery system and the headlight test checks out okay, you should check whether or not the battery is holding a charge, or if something on the vehicle is discharging it.
Perform A Load Test
To pass a load test, the battery must maintain 9.6 volts at 15 seconds when tested at one-half the CCA rating and 70°F (or above). This test must be done with a true load (carbon pile) and not one of the hand-held testers that work off a conductance algorithm. The test must be run with the battery in a high state of charge. .
