Energy of a Car Battery. [close] A battery is a device that converts chemical energy into electrical energy. A dry-cell flashlight battery consists of an electric cell, but larger batteries are made up of a group of cells that are connected to act as a source of direct electric at a given voltage.
A battery can change chemical energy to electricity by putting certain chemicals in contact with each other in a specific way. Electrons, which are small parts of an atoms, will travel from one kind of chemical to another under the right circumstances. When electrons flow, this makes an electrical current that can power something. What a battery does is put the right chemicals in the right relationships, and then puts a wall between them. Only when the two sides of a battery are connected by a wire or another conductor can the electrons flow.
