A battery uses basically lead and lead acid to cause a chemical reaction that produces the required voltage that a vehicle uses to run the vehicle electrical systems. The amount of material put into the battery when it was made will allow a vehicle battery to store and produce the required voltage needed to sustain a vehicles electrical system for about 3 to 5 years before a replacement battery is needed. Here is a very good explanation of how a battery works with a car’s electrical system.
