Abstract: The invention is a jump starting system for conducting a charging operation with various combinations of two automotive batteries in which one or both batteries is either a conventional battery, a battery with embossed electrical contact sockets, or a battery with internal electrical contact slots, where electrical connection between batteries is established by means of a battery jumper plug cable having four electrical jumper plugs electrically attached to respective ends of a positive insulated conductor and a negative insulated conductor.

Abstract: An automotive battery includes positive and negative battery contact sockets on the battery surface, each battery contact socket having a socket shell slot in a socket shell such that a polarized electrical connector prong inserted into a designated socket shell slot makes electrical contact with the corresponding battery terminal.

Abstract: An automotive battery includes a positive contact slot in a battery housing, the slot opening into a positive slot encasement inside the battery for insertion of a positive electrical prong for electrical connection to a contact region on a positive battery post; and, a negative contact slot in the battery housing, the slot opening into a negative slot encasement inside the battery for insertion of a negative electrical prong for electrical connection to a contact region on a negative battery post.
