Calling for roadside assistance to jump your dead battery is easy but not always efficient. Knowing how to jump a dead battery could get you on the road sooner than than roadside assistance could reach you. You could also help someone else out of a tough situation. We here at Richard Karr Motors can help you easily jump a dead battery!
- Start by inspecting the batteries. Bulges, cracks, and leaks are a no-go.
- If everything looks good, identify the positive (red) and negative (black) terminals of each battery. Do the same for your set of jumper cables.
- Attach one end of the positive (red) jumper cable to the positive terminal of the dead battery. Next, attach the other end to the live battery’s positive terminal.
- The first end of the negative (black) cable attaches to the live battery’s negative terminal.
- Attach the other end of the cable to a section of unpainted metal beneath the hood. Avoid the battery itself. Look for a jumping post or unpainted engine bolts instead.
- If everything is secure, start the car with the live battery and let it idle for a few minutes.
- Start the car with the dead battery. If it turns over, let both vehicles idle for a few minutes before disconnecting. If it doesn’t, call for help or wait a few minutes longer and try again.
To disconnect the cables, remove them in the opposite order you attached them.
