The main bragging point of this utipower voltmeter is its accuracy in determining the battery meter and voltage meter of a device.
Rv battery voltage meter.
This 12 v lead acid meter has a maximum working current of 5ma and can be easily change between two models.
Resting fully charged 12 volt batteries are around 12 8 12 9 volts and flat dead ones are at 12 0 volts so 12 4 volts on a resting battery means it s about 50 charged.
To determine if the alternator is charging your batteries hook the multimeter leads to the positive and negative cables that supply power to the rv.
Start the motor and the voltage should jump up to 13 8 volts.
