The difference between primary and secondary cells :
1. Primary cells can only be used once because the chemical reactions that supply the electrical current are irreversible while secondary cells can be  charged and reused.
2. Primary cells are typically lighter and smaller  thus traditionally more suited for portable applications while secondary cells are traditionally less suited for portable applications.
3. Primary cells are not ideally suited for heavy load while secondary cells have superior high discharge rate performance at heavy loads.
