When Jumping a Dead Battery, Which Car Do You Start First?

Jumping a dead battery is a simple and effective way to get your vehicle back on the road when faced with a dead battery. However, it’s important to know the correct way to jumpstart a car to avoid any mishaps or damage. One common question that arises during this process is, “Which car do you start first?” Let’s delve into the answer and explore some other frequently asked questions about jumpstarting a dead battery.

When jumpstarting a dead battery, it is recommended to start the car with the working battery first. This is because the car with the working battery will provide the power needed to jumpstart the dead battery. Here’s a step-by-step guide on how to properly jumpstart a dead battery:

1. Park both cars close enough for the jumper cables to reach both batteries but make sure they are not touching each other.
2. Turn off both cars and ensure all electrical components are switched off.
3. Locate the positive (+) and negative (-) terminals on both batteries.
4. Attach one end of the red (positive) jumper cable to the positive terminal of the dead battery.
5. Connect the other end of the red (positive) jumper cable to the positive terminal of the working battery.
6. Attach one end of the black (negative) jumper cable to the negative terminal of the working battery.
7. Connect the other end of the black (negative) jumper cable to a metal part of the dead car’s engine, away from the battery.
8. Start the car with the working battery and let it run for a few minutes.
9. Try to start the car with the dead battery. If it starts, let both cars run for a few more minutes.
10. Carefully disconnect the jumper cables in the reverse order: black (negative) from the dead car’s engine, black (negative) from the working battery, red (positive) from the working battery, and finally, red (positive) from the dead battery.
11. Keep both cars running for at least 10-15 minutes to allow the alternator to charge the dead battery.
12. Afterward, turn off both cars and carefully close the hoods.
