How to Jump a Dead Battery

Jumping a Car Battery

Getting stuck on the side of the road with a dead battery isn’t a situation many people hope to wind up in. Calling roadside assistance is easy, but knowing how to jump a dead battery could get you back on the road sooner. While jumping a dead battery may seem like a daunting task, have no fear! Here are nine simple steps to jump a dead battery:

  1. Park both cars nose to nose. Leave enough space so that you can walk between them.
  2. Inspect the batteries. If you see any corrosion or bulges, don’t try to jump it. Call for assistance instead.
  3. If everything looks good, start by identifying the positive (red) and negative (black) terminals of each battery. Do the same for the jumper cables.
  4. Attach one end of the positive (red) cable to the positive terminal of the dead battery. Attach the other end to the live battery’s positive terminal.
  5. Attach the negative (black) cable to the live battery’s negative terminal. The other end of the negative cable attaches to an unpainted piece of metal under the hood. Avoid the battery and watch out for belts and fans. Jumping posts and unpainted engine bolts are perfect to use in this step.
  6. Make sure all the cables are secure, and then start the car with the live battery.
  7. After idling for a few minutes, start the car with the dead battery. If it starts, remove the cables. If it doesn’t, call for roadside assistance or wait a few more minutes and try again.
  8. Detach the cables in the opposite order you put them on.
  9. Remove the cables, close the hoods and you’re good to go!

Remember: If you don’t think you can jump a dead battery by yourself, then call a professional.  If you have questions about this process or need assistance, feel free to reach out to us at Sun State Ford!
