What are the Functions of a Battery

A lead acid storage battery is an electrochemical device that produces voltage and delivers electrical current. The battery is the primary “source” of electrical energy used in vehicles today.

It’s important to remember that a battery does not store electricity, but rather it stores a series of chemicals, and through a chemical process electricity is produced.

Basically, two different types of lead in an acid mixture react to produce an electrical pressure called voltage. This electrochemical reaction changes chemical energy to electrical energy and is the basis for all automotive batteries.
