Confidence votes 1.7K. Assuming we're talking about the `usual' 12 volt car battery' the resting voltage should be around 11 to 11.5 volts. Under charge it's as high as 15 volts as supplied from the alternator,and most cars won't start if the voltage is under 10.5 to 11.5 volts. The term `12 volt battery' is what's referred to as, `nominal' or `in name only' as a general reference and not meant to be an accurate description.
CCA measurements assure that the battery has sufficient power to crank the engine, especially when cold. Typical CCA readings for a car range from 350 to 600A and higher for trucks. SAE J537 specifies that a battery with a CCA reading of 500A can deliver 500A at 18C (0F) for 30 seconds without dropping below 7.2 volts.
