ABSTRACT:
A battery charging system is provided including a charger and a rechargeable battery of "standard" size and configuration. The rechargeable battery bears a special indicia that is sensed by the charger as a precondition to enabling the charging circuit of the charger. The indicia-bearing battery can thus be used in place of "standard" non-rechargeable batteries in battery using products of various sorts, but non-rechargeable batteries, lacking the special indicia, cannot be charged in the charger. Potential damage to the charger or product and other adverse effects associated with charging of non-rechargeable batteries is thus avoided.
