ABSTRACT:
A pair of jumper cables for connecting between weak and strong batteries for transmitting power to jump-start a vehicle wherein the cables include a protective feature to isolate an electric spark from the general area of the batteries to prevent explosion. The cables comprise a first, continuous conductor cable adapted with clamps for attachment to the negative terminals or ground voltage of the respective batteries. A second, two-segment insulated conductor cable is provided having two medial and two distal ends, wherein each of the distal ends includes a conductive clamp for attachment to the positive terminals of the battery. The remaining medial ends of the positive cable are adapted for mutual, releasible attachment by an alligator clamp fixed at one of the medial ends. The remaining medial end is configured in size and shape to permit its firm grip within the opposing medial clamp.
