A pair of generally parallel, electrically conductive and ferrous material plates are provided and permanent magnets structure is sandwiched between the plates. An elongated electrically conductive threaded fastener includes a portion thereof projecting outwardly from the side of one of the plates remote from the other plate and may be removably threadedly anchored within an endwise outwardly opening bore formed in a recessed battery post. An electrically conductive member is also provided to which one end of the battery cable may be electrically connected and the contact member includes at least generally one planar side. The contact member is positionable with the planar side thereof abutting, spanning and magnetically attracted to a pair of side marginal edges of the plates which are disposed in the same plane.
