Question

Daniel cell is a primary cell while lead storage cell is a secondary cell. Write any one difference between primary cells and secondary cells.

Answer 1

Primary cells do not have a free-flowing electrolyte. Because of that such batteries are often called dry cells and cannot be used again.

On the other hand, secondary cells usually contain a liquid electrolyte, earning them the name wet cells. After secondary cells have completely discharged, they can be recharged and used again.

Examples of primary cells include the types of batteries used for children’s toys, radios and similar consumer electronics products. Car batteries and standby power sources are usually secondary cells.
