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.
