ABSTRACT:
Described is a system for indicating the state of charge of a battery comprising a safety cover with an opening and a battery which can be placed in the safety cover in two orientations. One marking on the battery indicates the battery has been charged and the other marking indicates the battery has been discharged. Only one of the markings shows through the opening when the safety cover is placed on the battery in one orientation, and only the other marking shows through the marking when the safety cover is placed on the battery in the other orientation. The mnemonic system is easy to manufacture and easy to use.
