How long will a car battery last after its recharged?
After a car battery is recharged with a jump start, it generally will last long enough to drive to an auto service center for battery maintenance or replacement.

A new car battery is fully charged by the alternator after driving 20 to 30 minutes without stopping.Source:Auto Mechanics Frankie’s Garage: How to Recharge a Dead BatteryEdmunds Inc.
