2007 BMW 530 6 cyl All Wheel Drive Automatic 14500 miles
Do you know how long it takes for a car to recharge the battery for what was consumed during a normal start? I found the following figures on the Net and they seem about right to me for worse case.
Discharge: 200 amps for 5 seconds = 0.3 AH
Charge: 0.3 AH, 20 amps = 1 minute
So basically, once the car is cranked and started, 1-2 minutes later the battery should be recharged. Is that correct?
have the same problem?
