Introduction
Knowing how to jump start a car is a basic but very useful skill for every driver. A dead car battery can happen anytime, whether you are at home, at work, or stuck on the road. Learning the right way to jump start a car can save time, money, and stress.
In this guide, you will learn how to jump start a car safely, what tools you need, common mistakes to avoid, and what to do after your car starts. The steps are simple and easy to follow, even for beginners.
What Does It Mean to Jump Start a Car?
Jump starting a car means using power from another vehicle or an external power source to start a car with a dead battery. The working battery gives enough energy to start the engine of the dead car.
Understanding how to jump start a car is important because a weak or dead battery is one of the most common reasons a car will not start.
What You Need to Jump Start a Car

Before starting the process of how to jump start a car, make sure you have the right tools.
Jumper Cables
These are thick insulated cables with metal clamps on each end.
A Working Vehicle or Power Source
You need another car with a healthy battery or a portable jump starter.
Safety Gloves (Optional)
Gloves can help protect your hands while handling cables.
How to Jump Start a Car Step by Step
Now let’s go through the most important part: how to jump start a car safely and correctly.
Step 1: Position the Vehicles Correctly
Park the working car close enough so the jumper cables can reach both batteries. Both cars should be in park or neutral with engines turned off.
Step 2: Identify the Battery Terminals
Each battery has two terminals:
- Positive terminal marked with a plus sign (+)
- Negative terminal marked with a minus sign (-)
Correct identification is very important when learning how to jump start a car.
Step 3: Connect the Jumper Cables Properly
Follow this order carefully:
Connect the Red Cable to the Dead Battery
Attach one red clamp to the positive terminal of the dead battery.
Connect the Red Cable to the Good Battery
Attach the other red clamp to the positive terminal of the working battery.
Connect the Black Cable to the Good Battery
Attach one black clamp to the negative terminal of the working battery.
Connect the Black Cable to a Metal Surface
Attach the final black clamp to an unpainted metal surface on the dead car, away from the battery.
This step reduces the risk of sparks and is essential when learning how to jump start a car safely.
Step 4: Start the Working Car
Start the engine of the working car and let it run for a few minutes. This allows power to flow into the dead battery.
Step 5: Start the Dead Car
Try starting the car with the dead battery. If it does not start right away, wait a minute and try again.
Once the engine starts, you have successfully completed the main steps of how to jump start a car.
Step 6: Remove the Jumper Cables Carefully
Remove the cables in the reverse order:
- Black cable from the metal surface
- Black cable from the working battery
- Red cable from the working battery
- Red cable from the previously dead battery
Be careful not to let the clamps touch each other.
What to Do After Jump Starting a Car
Knowing how to jump start a car does not end when the engine starts.
Let the Engine Run
Keep the car running for at least 15 to 30 minutes so the battery can recharge.
Avoid Turning the Engine Off Too Soon
If you turn the car off immediately, it may not start again.
Drive the Car
Driving helps recharge the battery better than idling.
