How many miles are needed to charge car battery?
Car batteries get re-charged by the alternator. If your battery recently went dead, "miles" is not what is measured to recharge the battery, "time" is used. I'd leave the car running for 15-30 minutes. Driving for this amount of time too is fine. If the battery goes dead again, probably a bad battery or bad alternator, or sometimes a bad alternator makes the battery go bad and they both need repaired. (typically a new alternator is $120 - $200)
