Abstract:

Extendable jumper cables for transferring electrical energy from a charged battery to a discharged battery include a first short cable having a clamp end that detachably connects to the charged battery, and a plug end that detachably connects to a cooperating plug end of a second short cable. The second short cable includes a clamp end that detachably connects to the discharged batter. The plug ends include cable connection fittings that allow the first and second cables and to be connected together to form typical jumper cables. The plug ends further include respective plugs that cooperate to receive corresponding plugs of an extension cord to increase the length of the extendable jumper cables to electrically connect the batteries together when the distance separating the batteries is greater than the combined length of the first and second short cables.
