A battery is a device that can store energy in a chemical form and convert it into electrical energy when needed. There are two fundamental types of chemical storage batteries: (1) The rechargeable, or secondary cell. (2) The nonrechargeable, or primary cell. They both discharge energy in a similar fashion, but only one of them permits multiple ...
