If your battery has died, you may be able to use jumper cables to jump start it from the second vehicle. Do you know how to use jumper cables correctly? In this instruction, we will show you how to easily revive your car using starting cables.
What you will need:
- Jumper cables
- Second car
How to Use Jumper Cables:
- Make sure both batteries are of similar voltage or you risk damaging electrical components.
- Park the two cars, the dead car and the boosting car, close to one another. Make sure that they’re not touching each other.
- Place both vehicles in a park or neutral and shut off the ignition in both cars.
- Connect one red clamp to the positive (+) battery post of the dead battery.
- Connect the other red clamp to the positive (+) post of the good battery.
- Connect one black clamp to the negative (-) post of the good battery.
- Connect the other black clamp to some large metallic part of your car’s engine block. Never connect it to the negative (-) post of the dead battery, because this causes sparking which could ignite battery gases.
- Start the working vehicle and let the engine run for a few minutes.
- Start the dead car’s engine and let it idle for a few minutes. If it won’t start, make sure that the cables are properly connected and try it again. If it still won’t start, there can be other problem and it’s time to call car service.
- If your dead vehicle is alive, disconnect the black jumper cable from the revived engine. Then disconnect the black jumper cable from the good car.
- Remove the red jumper cable from the good car. Then remove the red jumper cable from the revived car.
- If the jump works and your car starts, don’t shut off your engine! Drive around for at least 15 minutes to recharge your battery. If the car won’t start the next time you use it, the battery isn’t holding a charge and needs to be replaced.
