Each cell in a battery (just after a full charge) is 2.2 volts. After resting for 12 to 24 hours, the voltage drops to 2.1 volts per cell. So, a charged but rested 12-volt battery will actually be around 12.6 volts after charge. And a 6-volt battery will read 6.4 volts. It''s important to understand this, so you don''t get a false reading.
