How to Tell If a Deep Cycle Battery Is Bad

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.

What You Need to Know About Car Battery Voltage

Standard car batteries are listed as 12-volt batteries. However, this is rounding down, as a car battery should have a "resting voltage" – which is to say, the amount of voltage it has when it''s turned off – of 12.6 volts. That voltage increases when the car is running.

Battery Discharge: solar battery bank discharge explained
