An automobile’s battery provides the electricity necessary to start the car and to run its electrical equipment. Although an automobile battery is normally charged by the car’s alternator while the car is running, there are times when the battery dies for various reasons and needs to be connected to a charger. When jumpstarting a car you essentially give the dead battery just enough boost to start the engine and then rely on the alternator to charge the battery the rest of the way. When using a battery charger, you allow the battery to charge all the way before it will be used again.
