Abstract: A charger and battery combination for recharging batteries has a pair of snap arms for retaining a battery within the pocket of the charger. When the battery is inserted into the charger pocket, the snap arms provide a downward force against the battery, thereby ensuring a sound electrical connection between the battery and electrical contacts disposed within the pocket. In one embodiment, the charger pocket includes a pair of channel apertures in which the snap arms are placed. Upon battery insertion, a flex member of the snap arm deflects, thereby allowing a mating feature of the battery to pass. When the battery is fully inserted, a coupling member of the snap arm exerts a force against the battery, thereby pushing the battery towards the bottom of the pocket.

Abstract: A battery housing is described comprising a frame, a top cover, and a bottom cover, wherein the frame has a ledge at its bottom, and an arch formed on one or more walls of the frame. The top cover has one or more rod-shaped projections protruding downward from the bottom side of the top cover, each projection having a ridge at the distal end of the projection. The bottom cover of the housing is wedged between the ledge and the arch, and the top cover of the housing fits onto the frame. Each rod is slid through a corresponding opening in the arch, and the ridge at the distal end of each rod slides through and past the opening of each arch, locking the rod in place vis-a-vis the arch.
