An electrical connection system between a battery (4) and a battery charger (6) comprising on the battery side an male pin (8) having a first end (10) attached to the battery and a second free end (12) including a domed shaped positive pole (14) and an second negative pole annular shaped (16) with a non linear external surface. Both poles are concentrically arranged and separated by annular insulation member (18). The battery charger connector (6) comprises a recess (7) having a base (9), side walls (11) and an open end (13). It includes a flat magnetic positive electrical terminal (20) adjacent to the base (9) and at free end (21) of a docking location. Positive terminals (20, 14) of the battery and battery charger have opposite magnetic polarity. The charger also includes three spring clips shaped negative terminals (22) protruding outwardly from base (9) and located radially outwardly from central terminal (20).
