Battery Jumper Cable

Battery jumper cables are a type of electrical cable used to jump-start a vehicle with a dead battery. They are typically made of heavy-duty insulated copper wire with clamps on each end. One end of the cable is connected to the positive terminal of a working battery, while the other end is connected to the positive terminal of the dead battery. The negative terminal of the working battery is then connected to a metal part of the vehicle with the dead battery, such as the engine block, and the vehicle can be started using the power from the working battery. Battery jumper cables are an essential tool for emergency situations when a vehicle's battery has died and need to be recharged quickly.
