• A primary cell is a battery that is designed to be used once and is discarded and cannot be recharged with electricity and reused like a secondary cell rechargeable battery • The electrochemical reaction occurring in the cell is not reversible rendering the cell unrechargeable In other words the means by which they discharge there energy
