How batteries work

A battery is a container—inside it are chemicals that react to metal or each other. Their reaction releases energy in the form of an electric current. The battery directs that current (electrons) to a negative terminal. The positive terminal on the other end of the battery absorbs the current. The electrons leave the negative terminal when it’s connected to something like a flashlight, light up the bulb, then return to the battery at the positive terminal.
