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?

By providing current rechargeable batteries can be recharged. Chemicals inside the battery react and generate electricity, but once that chemical reacts completely with no electricity left, then it is called a discharged battery. But a discharged battery can be used again by reversing the reaction that produces electricity. That is, if we reverse the reaction that uses up all the chemicals inside the battery and produces electricity, the chemical will start generating electricity again. This is the function of a rechargeable battery.
