How Far Should You Drive To Charge A Car Battery. See how much charge is lost in that week. Then just before you are going to drive it measure it again.
It varies depending on how much charge is in your battery before you start driving and your driving style. If the battery is deeply discharged 15-30 minutes on a 40-amp charger will provide charge and give the alternator a chance to finish charging the battery while driving your car. If your car started after you did a jumpstart you would have to let it run for a few minutes to charge the car battery further.

A car alternator charge tapers off as the batery charges up so the final 20 will take hours. You have to drive your car for about thirty minutes. That is one reason you want to drive several miles afterward so the battery has a chance to. Cold batteries will not recover quickly when being recharged in sub-freezing temperatures.
