How to Charge a Car Battery by Driving
- 1). Turn off anything within the vehicle that uses power. This includes radios, air conditioning units and interior lights. Ideally, charge the battery during the day and in good weather. This way you can avoid using your headlights and windshield wipers as well.
- 2). Perform a push start of your car with the dead battery. Press in the clutch and go into first gear. Release the brake and have another person start pushing the car. Release the clutch and give it a little gas to get the car running.
- 3). Head to an area where you can drive at a consistent speed. Highway driving is ideal for charging a depleted battery. City driving where you are constantly stopping and going will not provide an even charge.
- 4). Continue to drive for half an hour to charge the battery. Keep all power sources off during this time period. You can drive longer, but a half an hour is needed in order to give the battery a good enough charge.
