Abstract: A base plate includes a planar member. Two rods extend from the planar member, each of the rods having a free end. A battery includes two bores there-through, the bores positioned and configured to receive the rods when the battery is positioned on the planar member. Two first terminals protrude from the planar member. Two second terminals are recessed within the battery and are configured and positioned to contact the first terminals when the battery is positioned on the planar member. Two third terminals are configured for connection to a vehicle's battery cables and are electrically connected to the first terminals. A cap threadedly connects to the free end each rod to secure the battery on the base plate.
