A charging system for rechargeable batteries, e.g. of the 9 volt type, includes a charger and an adapter module for mechanically and electrically interconnecting the charger to a 9 volt size battery. The adapter includes a projection or key extending upwardly from and adjacent the battery terminals to block connection of all batteries except those batteries with key receivers. In this manner, only rechargeable batteries with such receivers may be charged thereon. Finger grips on the adapter are designed to generate a moment for detachment from the charger.
