What do you understand by secondary cells?

उत्तर १
Secondary cells are cells which provide current as a result of reversible chemical reactions. It converts electrical energy into chemical energy when current is passed in it (i.e., during charging), while it converts chemical energy into electrical energy when current is drawn from it (i.e., during discharging).
उत्तर २
Secondary cells are those that can be recharged by passing a direct current through them. These activity cells are repeated. They may be recharged after each use, allowing for repeated use. Because secondary cells may store electrical energy as chemical energy, they can be referred to as storage cells or accumulators.
