How to Jump a Dead Battery

How to Jump a Dead Battery

Even if you have roadside assistance, knowing how to jump a dead battery is vital when you’re on the road. Whether you’re commuting home or heading out on a vacation, waiting for help to arrive is the last thing you want to do. Instead of waiting for roadside assistance to show up, you could jump the dead battery yourself. If you don’t know how, let us here at Wiesner of Huntsville help you out!

  1. Start off by identifying the positive and negative battery terminals and jumper cables. The positive sides are normally red while the negative are usually black.
  2. Once you’ve identified the positive and negatives, it’s time to start connecting cables. Attach the positive end of the jumper cable to the dead battery’s positive terminal. Attach the other end to the live battery’s positive terminal.
  3. Attach one end of the negative cable to the live battery’s negative terminal.
  4. Attach the other end of the negative cable to an unpainted piece of metal near the battery. Jumping posts and engine bolts are good spots.
  5. Make sure everything is secure, then start the car with the live battery.
  6. Let it idle for a few minutes.
  7. Start the car with the dead battery. If it starts, move on to the next step. If it doesn’t, let the car idle for a few more minutes then try again or call for help.
  8. Let both cars idle for a few minutes before disconnecting cables.
  9. Disconnect the cables in the reverse order you attached them.

We here at Wiesner of Huntsville wish you safe travels no matter where you’re headed.
