A charging system is provided for use in an energy-using device operable from an external source of A-C power and from either batteries of either the rechargeable or non-chargeable type. The charging system effects charging of batteries of the rechargeable type upon connection of the energy-using device with the external source of A-C power. The charging system includes a charging adapter for insertion with rechargeable batteries into the energy-using device. Removal of the charging adapter from the energy-using device is effective to preclude charging of batteries of a non-rechargeable type.
