What Is An Acceptable Amp Draw On A Car Battery. You should be getting 14 volts. Cougar October 7 2008 220pm 13.
Anything past these amounts indicates an electrical issue and should be addressed by a mechanic. If there is an electrical short in the vehicle or a malfunctioning accessory it could draw more than its normal load causing a large drain on the battery. A normal amount of parasitic draw for older cars is a reading less than 50-milliamp.
Anyway I did a volt test on the drivers side battery last night the opposite side that was tested by Advance and it showed 103 volts which shows me the battery has an issue or something drained it bad.
The draw on the battery should only be a few milli-amps. Although I have checked the parasitic draw on my Excursion in the past Id never photographed that test. In short we are talking about literal Thousands of Amps for a dead short. Parasitic loads can run 20 to 120 milliamps.
