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.
