Battery jumper cable
First Claim
1. A battery jumper cable comprising:
- a first electrically insulated flexible low-voltage conductor having a first end portion and a second end portion electrically connected to a first pair of electrically insulated pole pliers and a second pair of electrically insulated pole pliers, respectively;
a second electrically insulated low-voltage conductor having a first end portion and a second end portion electrically connected to a first pair of electrically insulated pole pliers and a second pair of electrically insulated pole pliers, respectively;
a third electrically insulated conductor connecting the first low voltage conductor and the second low-voltage conductor in close proximity to said first pairs of pole pliers; and
a fourth electrically insulated conductor connecting the first low voltage conductor and the second low-voltage conductor in close proximity to said second pairs of pole pliers;
each of said third and fourth conductors comprising a voltage-dependent resistor having a forward voltage which exceeds the operating voltage of conventional starting batteries for motor vehicles, so as to provide a current flow path for short time peak voltages and block current flow for battery operating voltages.

Abstract
A battery jumper cable comprises a first electrically insulated flexible low-voltage conductor having two end portions each electrically connected to a pair of pole pliers and a second electrically insulated flexible low-voltage conductor having two end portions each electrically connected to an insulated pair of pole pliers. To prevent the occurrence of high peak voltages which may affect vehicle electronics during a jumper operation between a powering storage battery of the one vehicle and a discharged storage battery of another vehicle, there is provided at least one electrical connection between the first low-voltage conductor and the second low-voltage conductor. This electrical connection has at least one voltage-dependent resistor exhibiting a forward voltage in excess of the operating voltage of conventional starting batteries for automotive vehicles. The voltage-dependent resistor may be accommodated within a housing.
