A rechargeable battery, or a storage battery, is a kind of battery that can be restored to full charge by the use of electrical energy. It is also called Secondary cell. A battery that is not rechargeable is called a primary cell, or disposable battery. Like other batteries, rechargeable batteries can be recycled.
A rechargeable battery, compared with a disposable battery, has many advantages because it can be reused many times. It makes less pollution because it does not get thrown away as quickly. Using them can cost less money, because people have to buy new batteries less often. Rechargeable batteries also have some disadvantages. They cost more money to manufacture, and contain more toxic chemicals than disposable batteries.
