Where Should Battery Gauge Be On Car. 2 Gauge Buy 2 Gauge wire. The battery gauges on most vehicles I have owned stays around 13 to 14 volts and doesnt move much unless something that consumes a lot of power is turned on.
The ideal car battery voltage with the engine running is between 137 and 147V. To get a true voltage reading of the cars battery it is important to measure the voltage after the car.

Clean them and try again. A battery cable with the wrong gauge is one of the most common issues in improper installations and can pose a much greater risk than some realize. If it is somewhere in the middle it should be ok but the dash gauge is not totally accurate. The alternator how much charging the battery needs and therefore how much.
