Question

Why do we use secondary cells in a daily life​

Answer 1

Explanation:

These cells are used only in devices that require a relatively low supply of electric current (such as hearing aids and watches). These are batteries that can be recharged after use by passing current through the electrodes in the opposite direction, i.e. from the negative terminal to the positive terminal.
