A battery charger having a housing, a transformer in the housing and separate sets of external terminals situated on recessed surfaces at opposed sides of the housing, the external terminals being connected to separate secondary windings of the transformer so that the terminal sets are oppositely phased electrically. Blade connectors spaced apart along the line of spacing between opposed sides are electrically connected to the primary winding and extend through the housing for acceptance by an external electrical receptacle. A grounding pin being mechanically affixed to the transformer core structure and similarly extending through the housing.

A battery charger comprising: a housing having first and second sets of external terminals located for simultaneous connection to the corresponding terminals of separate external battery circuits to be charged, said external terminals each including means for releasably supporting a respective battery circuit when the corresponding terminals of said battery circuit are connected for charging, a transformer inside the housing comprising a core member having a frame extending therearound, a primary winding and two secondary windings each having a pair of end terminals, such terminals being connected internally of the housing to separate ones of a respective set of external terminals, blade connectors electrically connected to said primary winding and extending to said housing for acceptance by an external electrical receptacle, and a ground pin connector adapted for acceptance by the external electrical receptacle, said ground pin connector being mechanically affixed to said core frame and extending therefrom through said housing, said connectors being adapted to support said charger and said external battery circuits when said connectors are disposed in the receptacle. A battery charger comprising a charger housing having two opposed, generally parallel sides for the mounting of separate battery modules holding cells to be charged, said sides having recessed module-receiving surfaces, first and second external terminals on each of said recessed surfaces for connection to mating terminals of the battery module, said terminals being formed to releasably support the module connected thereto, a transformer at the interior of said housing having a core member, a primary winding and at least one secondary winding wound on said core member, said secondary winding having end terminals connected respectively to the external terminals on at least one of said sides, a pair of blade connectors electrically connected to said primary winding extending from a side of said housing intermediate said opposed sides for acceptance by the line contacts of an electrical receptacle, said blade connectors being spaced apart in the direction of spacing between said opposed sides, and a grounding pin affixed to said transformer core member and extending therefrom through said housing for acceptance by the ground contact of the electrical receptacle.
