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.

You accidentally left your headlights on do you need a jump or can you wait it out?

Hmmm, unless it is something new, I've never heard of a battery that will recharge itself when the engine is not running. You will either have to connect a charger to it or jump-start the vehicle. To jump-start, follow these directions to avoid any sparks and cause possible damage to the electronic components: 1. Connect one end of the positive jumper cable to the positive post of the "DEAD" battery. 2. Connect the other end of the positive jumper cable to the positive post of the "GOOD" battery. 3. Connect one end of the negative jumper cable to the negative post of the "GOOD" battery. 4. Connect the opposite end of the negative jumper cable to GROUND on the "DEAD" vehicle. Start the "GOOD" vehicle and allow to run several minutes to boost the DEAD battery. After several minutes of boosting, start the "DEAD" vehicle and allow to run a couple of minutes before disconnecting the jumper cables. To disconnect the jumper cables, remove IN REVERSE ORDER of connection.
