To safely use a ring jumper cable to jump-start a vehicle, first ensure both vehicles are turned off. Connect the positive () ring to the positive terminal of the dead battery and the negative (-) ring to a metal surface on the car with the charged battery. Start the working vehicle and let it run for a few minutes. Then try starting the dead vehicle. Disconnect the cables in reverse order once the dead vehicle starts.
