An automotive battery connection system, which includes a substantially cylindrical battery case acting as a terminal for an automotive battery. The battery case includes partitions defining a keyway for cables and a center partition dividing the battery case into two case pockets. A battery positive post is situated within one of the case pockets. A battery negative post is situated in the other of the case pockets. A substantially cylindrical plug is adapted to seat on the partitions of the battery case. The plug comprises a pair of sockets defined within its base, each socket defined within one of the plug pockets shaped identical to the battery positive post and the battery negative post and sized to have the battery positive post and the battery negative post securely seat therein. Therefore, cables terminating within the base of the plug are in conductive communication with the sockets.
