A rechargeable battery, also called 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 a secondary cell. A battery that is not rechargeable is called a primary cell or disposable battery. Like other batteries, rechargeable batteries can be recycled.
Compared with disposable batteries, rechargeable batteries have many advantages. They can be reused many times. They make less pollution because they do not get thrown away as quickly. Using them can cost less money, because people have to buy batteries less often. Rechargeable batteries also have disadvantages. They cost more to manufacture. They have more toxic chemicals than disposable batteries.
