Abstract: A vehicle battery system includes a battery for providing electric current to a starter of the vehicle through a first electrical cable, and for providing and receiving electric current to and from, respectively, a remote battery through a second electrical cable for recharging a certain one of the batteries. A casing of the battery has a pair of spaced electrodes incorporated therein which establish electrical contact with an electrolyte solution contained in the casing. A pair of universal plugs is embedded in the casing and is electrically connected to the electrodes by electrical conductors also embedded in the casing. Each universal plug includes a prong and a receptacle so that the plugs are engageable with other similar universal plugs in a single orientation for maintaining proper electrical polarity therebetween. A universal plug is attached to one end of both the first and second electrical cables for engaging the plugs of the system battery.
