Introduction
Without a working battery, your car won't start, leaving you stuck at home or stranded on the road. Car batteries are charged by an alternator that produces electricity while the car's running. Still, batteries sometimes lose some or all of their charge. You'll know when this happens because your car either won't start, or the starter motor will only turn over weakly when you turn the key.
Lots of short trips, or electrical components such as lights and radios left on for long periods while the car's not running are some of the most common reasons why a battery loses its charge. Battery issues happen to all vehicles eventually. Learn exactly how to charge a car battery, so when yours goes dead and your car won't start, you can get up and running again fast.
