What should a 12 volt battery read when fully charged?
That’s only a difference of 0.25 volts on each cell from fully charged to fully discharged. So a 12volt battery will measure at about 12.9 volts when it’s fully charged and about 11.4 volts when it is fully discharged. That’s a total of 1.5 volts that represents the full range of charge on a 12volt battery.
How can I test my battery?
