Abstract: Disclosed is a quick change battery drawer for rapidly substituting a fresh battery for an exhausted battery in the battery drawer of an external, battery powered therapeutic electrical stimulator while the stimulator continues to emit electrical stimulation to treat a patient. A push button is normally biased outward and a release member latches the battery drawer in the latched position through the interaction of first catches on the battery drawer and second catches on the release member. The terminals of a battery loaded in the battery drawer bear against and compress spring terminals that thereby spring load the battery drawer with a bias force and assist in keeping the battery drawer latched. When the release button is depressed, the first and second catches are disengaged, and the bias force acts to eject the battery and battery drawer forcefully into an ejected position where the battery drawer is prevented from completely ejecting from the side opening.
