Electricity-producing cells which use interaction of metals and chemical to create electrical current flow.
An electrical battery is a combination of two or more electrochemical cells used to convert stored chemical energy into electrical energy.
There are two types of batteries: primary batteries (disposable batteries), which are designed to be used once and discarded when they are exhausted, and secondary batteries (rechargeable batteries), which are designed to be recharged and used multiple times. (Wikipedia)
