Rechargeable battery

type of electrical battery which can be charged, discharged into a load, and recharged many times; device that stores energy

A rechargeable battery, also called a storage battery or a secondary cell, is a battery that can be recharged over and over again with electricity.[1] A battery that is not rechargeable is called a primary cell or disposable battery.[2] It is thrown away after it no longer works. The voltage of rechargeable batteries can be restored by passing an electric current through the battery. Car batteries, for example, work this way..[3][4]

Rechargeable batteries are not always chosen. Each battery costs more to make, and has more dangerous chemicals than disposable batteries.

Rechargeable batteries can be used for many smaller electronics such as MP3 players and flashlights. Almost all mobile phones and laptop computers use them. They are also used for car batteries.
