When the chemicals in the electric cell are used up, the electric cell stops producing electricity. The electric cell is then replaced with a new one. In case of rechargeable batteries (such as the type used in mobile phones, camera and inverters), they are used again and again. How?

Answer:

The chemicals present in rechargeable batteries can be restored by passing suitable current in the opposite direction to these batteries, so they are used again and again.
