How to Jumpstart a Car: A Step-by-Step Guide


Jumpstarting a dead car battery could seem like a challenging task, but it does not have to be. In this article, we will guide you through the process of jumpstarting a car safely and correctly. But before we go ahead, it is essential to recognize that not all car batteries are the same. Some vehicles may require a different approach, and it is necessary to consult your car manual before attempting to jumpstart it.

Know the Basics

The first step in jumpstarting a car is to understand the critical components involved in the process. You will require a functioning vehicle, jumper cables, and safety gear such as gloves and protective eyewear. If you do not have jumper cables, you can purchase them from a local auto supply store. It is also crucial to ensure that both vehicles have the same voltage output, or else it may result in damage to the vehicle’s electrical system.

Step-by-Step Guide

Step 1: Position the Cars
Position both cars facing each other, close enough that the cables can reach from the dead battery to the live one. It is crucial to have sufficient distance between the two cars to avoid touching.

Step 2: Turn Off Both Vehicles
Ensure both vehicles are turned off before connecting the cables. The live vehicle should not be running while you attach the cables.

Step 3: Connect the Jumper Cables
1. Begin by attaching the red cable to the positive terminal on the dead battery.
2. Connect the other end of the red cable to the positive terminal on the live battery.
3. Next, connect the black cable to the negative terminal on the live battery.
4. Connect the other end of the black cable to a metal part of the dead car. It is crucial to avoid the negative terminal of the dead battery, which can cause a spark.

Step 4: Start the Live Car
Start the vehicle with the live battery and let it idle for a few minutes. This allows the battery to charge and build-up capacity. You do not have to rev the engine of the live vehicle.

Step 5: Start the Dead Car
Attempt to start the dead car. If it does not start immediately, let it charge for another couple of minutes. Once it starts, leave it idling for a few minutes to ensure that the battery is fully charged.

Step 6: Disconnect the Jumper Cables
1. Start by disconnecting the black cable from the metal part of the dead vehicle.
2. Remove the black cable from the negative terminal from the live battery.
3. Remove the red cable from the positive terminal of the live battery.
4. Finally, remove the red cable from the positive terminal of the dead battery.

Safety Precautions

It is essential to take necessary safety precautions before attempting to jumpstart a vehicle. Ensure that the vehicles are not touching, reduce the risk of sparks by connecting the cables in the right order, and avoid smoking near the battery. Always wear protective gear such as gloves and eyewear to prevent injury.


Jumpstarting a car is a simple process, but it requires careful attention to ensure that the task is completed safely and correctly. By following the step-by-step guide, you will be able to revive your dead battery and be on your way in no time.
