Abstract
A jumper cable which includes a receptacle mounted on, near or within a battery casing. The receptacle may include a socket having a pair of circular contacts on the inner circumference thereof electrically connected to battery terminals. The device may also include a cable having a plug on each end configured to mate with the receptacle socket. Such a plug may include a larger-diameter ring for engaging the upper contact and a smaller-diameter ring for engaging the lower contact when the plug is inserted into the socket. Accordingly, if a battery needs recharging, a plug is inserted into the receptacle associated with the dead battery and the opposing plug is inserted into a receptacle associated with a charged battery to establish electrical interconnection there between. Alternatively, an adapter having a socket and electrical clamps for grasping battery terminals may be used when a receptacle is not connected to one of the batteries.
