Safe Distance

After the cables are properly connected, make sure to double-check all the connections to ensure they are secure. Once you are confident in the connections, you can start the engine of the car with the working battery.

Allow the engine of the working car to run for a few minutes to charge the dead battery. While the dead battery is being charged, it’s important to keep a safe distance from the engine areas of both cars and avoid touching any metal parts.

After enough time has passed, try starting the car with the dead battery. If it starts, you can now safely disconnect the jumper cables starting with the negative cable clamps followed by the positive cable clamps.

Remember to drive your car for at least 20 minutes to allow the alternator to fully charge your battery. This will help prevent future battery issues and ensure a reliable start every time.

Connect the Jumper Cables

If you need to charge a car battery and revive a dead one, using jumper cables is a common method. Jumper cables allow you to jump-start your car by connecting your dead battery to another vehicle’s battery.

  1. Park the working vehicle next to the car with the dead battery, making sure the two vehicles are close enough for the jumper cables to reach.
  2. Make sure both cars are turned off and the keys are removed from the ignition.
  3. Open the hoods of both vehicles and locate the batteries.
  4. Identify the positive (+) and negative (-) terminals on both batteries. They are usually marked with a plus or minus sign.
  5. Connect one end of the red jumper cable to the positive terminal of the dead battery.
  6. Connect the other end of the red jumper cable to the positive terminal of the working battery.
  7. Connect one end of the black jumper cable to the negative terminal of the working battery.
  8. Finally, connect the other end of the black jumper cable to a metal part of the car with the dead battery, such as an unpainted metal surface.

Once all the jumper cables are connected properly, start the working vehicle and let it run for a few minutes. This will allow the charge from the working battery to transfer to the dead battery.

After a few minutes, try starting the car with the dead battery. If it starts, let both vehicles run for a while to ensure the dead battery is fully charged. If it doesn’t start, you may need to check the connections and try again.

Remember to remove the jumper cables in the reverse order in which they were connected. Disconnect the black cable from the metal surface first, then from the negative terminal of the working battery. Next, disconnect the red cable from the positive terminal of the working battery and finally from the positive terminal of the dead battery.

Jump-starting your car using jumper cables can be an effective way to charge a dead car battery and get your vehicle running again.

Start the Working Car

Once you have connected the cables to both car batteries, you can now start the working car. This car will be used to provide the necessary charge to revive the dead battery. Before starting the working car, make sure that all accessories such as lights and the radio are turned off. By doing so, you minimize the power draw from the working car’s battery, allowing more energy to be transferred to the dead battery.

Start the working car by turning the key in the ignition. Give it a few seconds to rev up and run at a normal idle speed. This will help ensure that the charging system is working properly and that the car is generating enough power to charge the dead battery.

Start the Dead Car

Once you have connected the charged car battery to the dead car battery, it’s time to start the dead car. Follow these steps to revive it:

Step 1: Make sure both cars are turned off

Before starting the dead car, it’s important to ensure that both cars are turned off. This will prevent any accidents or damage while working with the batteries.

Step 2: Start the charged car

Start the car with the charged battery and let it run for a few minutes. This will provide the dead car with the necessary charge to start.

Step 3: Try starting the dead car

Now, try starting the dead car. Turn the key in the ignition and see if the engine turns over. If it does, congratulations! You have successfully revived the dead car battery using another car’s battery.

If the dead car doesn’t start, you may need to try a different method, such as jump-starting the car using jumper cables and another running car. Refer to our “How to Jump-Start a Car” guide for more information on this method.

Remember, charging a dead car battery using another car is a temporary solution. It’s important to have the dead battery checked and replaced if necessary to avoid any future problems.
