Abstract
A battery charger for alternately receiving batteries having substantially different charging rate requirements in which the charger has contacts engaged by a battery pack to be recharged, for the purpose of carrying out such recharging. A difference in at least one of the charger contacts is engageable by one of the high and low charge rate battery packs, but not the other. Whether or not that one charger contact is engaged by a battery pack causes the battery charger to supply charging current at different levels to automatically charge such high and low charge rate battery packs at corresponding high and low charge rates.
