How to Jump a Car Battery

Jump start a dead car batteryHere at Pat Peck Kia, we know that accidents happen. No one plans on leaving an interior light on, a car door open, or their headlights on. However, something we can control is how prepared we are when these things inevitably occur.

Whether your battery needs a jump because of the above reasons or some other unexpected event, we want to make sure our fellow D’Iberville, Gulfport, and Hattiesburg area drivers know how to jump a car battery safely.

Step 1: Positive to Positive

For most jumper cables and batteries, the color red stands for positive and black is negative. A good rule to follow when jumping a car battery is to always hold the red clamp in your right hand and the black clamp in your left hand. This will help make sure that the positive and negative clamps don’t touch throughout the process.

The first step in jumping a battery is to connect the positive clamp to the positive terminal on the dead battery. Then, attach the other red clamp to the positive terminal of the working battery.

Step 2: Negative to Negative

The next step is to connect the negative cables. Attach the black cable to the good car’s negative terminal. On the disabled car, attach the final clamp to a clean, unpainted metal surface that isn’t touching the battery. This is called grounding.

Step 3: Jump-Start

Once all cables are attached and stable, start the working car and let it run for two to five minutes before trying the second car. If it doesn’t start right away, rev the working car’s engine a bit to give more power. When the second car does start, be sure to let it run for a few minutes to ensure the charge keeps.

Step 4: Safely Remove the Cables

All cables should be removed in the opposite order with which they were first applied while seeing to it that they don’t touch. All of this is to avoid any sparking.

Safety Precautions

When jumping a car battery, there are a few safety precautions to keep in mind. First, make sure the cars are close enough that the jumper cables can easily reach both batteries. Make sure the vehicles are not touching, too.

Once you have them where you want them, take the keys out of both ignitions and apply the parking brakes to make sure neither car moves while you’re jumping the battery. Also, be sure not to stand between the cars while the battery is being jumped.

Check the jumper cables to make sure they’re clean and in good working condition. Also, make sure both batteries are clean and have no cracks or leaks. If you notice a powdery film on the battery, use gloves to wipe it away.

Finally, you always want to consult your owner’s manual for any additional steps that might be required for your specific vehicle.
