What is a "jumper cable"?
A jumper cable is a set of thick wires used to connect a dead car battery to a charged one, allowing the car to start. It has metal clips at both ends: one set is connected to the dead battery, and the other to the working battery. Jumper cables are typically used when a vehicle’s battery loses power, and they provide the necessary boost of electricity to start the engine. It is important to follow the correct procedure when using jumper cables to avoid damage to the batteries or electrical system.
Examples
He kept a set of jumper cables in his trunk in case his battery ever died.
