The jumper cables with the wire brush are to be motioned to remove battery terminal corrosion, thereby providing for a better electrical connection. The device resembles a standard pair of jumper cables used to aid in jump-starting a motor vehicle with a dead battery and comprises a small wire brush located inside of each jaw area. The bristles are made of conductive steel or copper of a sufficient stiffness to clean any corrosion from the battery terminals as the clamps are being installed. Due to the conductive nature of the bristles, current will flow through the bristles as well as the clamp body, thus improving charging and starting ability. ## Claims ### Claim 1 A battery jumper system for cleaning battery terminals and grounded jumper connections, said battery jumper system comprising: first and second cables;
