What Voltage Is A 12 Volt Battery Fully Charged. How many volts should a good 12 volt battery read. There is a very big difference when a car battery drops even a small amount of voltage.
Volts on a resting battery means its 19 jun 2017 when the is fully charged. These voltages are appropriate to apply to a fully charged battery without overcharging or damage. The battery should read at least 126.
It should be somewhere between 128 volts fully charged and 121 volts 50 percent charged.
With experience one can accurately determine state of charge using a voltmeter. View the most popular hydrometer on amzn. These voltages are appropriate to apply to a fully charged battery without overcharging or damage. I put together the following battery state of charge chart which indicates the state-of-charge percent as it relates to battery voltage or specific gravity.
