How to Jump Your Car Battery: A Step-by-Step Guide
Dead car batteries can be frustrating, especially when you’re in a hurry or stuck in a remote location. However, with the right tools and knowledge, jumping a car battery is a relatively simple process that can get you back on the road in no time. In this article, we’ll walk you through the steps to jump-start your car battery safely and effectively.
Before You Start: Safety Precautions
Important: Before attempting to jump-start your car, make sure you follow these essential safety precautions:
- Wear protective gloves and safety glasses to prevent electrical shock.
- Make sure both vehicles are parked on level ground, with the engines turned off and in neutral or park gear.
- Set the parking brake on both cars.
- Turn off all electrical accessories (headlights, radio, etc.) in both vehicles to avoid a surge of power when the batteries are connected.
- Never jump-start a car with a damaged or cracked battery, as it can cause an explosion.
Gather the Necessary Equipment
To jump-start your car, you’ll need the following equipment:
- A set of jumper cables (also known as booster cables)
- Another vehicle with a working battery (donor vehicle)
- The owner’s manual for both vehicles (optional)
Step 1: Locate the Batteries and Identify the Terminals
Find the batteries in both vehicles and identify the positive (+) and negative (-) terminals. The positive terminal is usually marked with a “+” sign or a red color, while the negative terminal is marked with a “-” sign or a black color. (See Also: Does The Car Battery Charge While Driving)
| Terminal | Color | Marking |
|---|---|---|
| Positive (+) | Red | + |
| Negative (-) | Black | – |
Step 2: Connect the Jumper Cables
Connect the jumper cables to the batteries in the following order:
- Attach one end of the positive (red) jumper cable to the positive terminal of the dead battery.
- Attach the other end of the positive (red) jumper cable to the positive terminal of the donor vehicle’s battery.
- Attach one end of the negative (black) jumper cable to the negative terminal of the donor vehicle’s battery.
- Attach the other end of the negative (black) jumper cable to a metal surface on the dead vehicle’s engine or frame, away from the dead battery.
Important: Never connect the negative (black) jumper cable to the negative terminal of the dead battery, as it can cause a spark and potentially ignite hydrogen gas.
Step 3: Start the Donor Vehicle
Turn the key to start the engine of the donor vehicle. Let it run for a few minutes to charge the dead battery.
Step 4: Start the Dead Vehicle
Once the dead vehicle’s battery has been charged a bit, try to start the engine. If it doesn’t start right away, let the donor vehicle’s engine run for a few more minutes and try again.
Step 5: Remove the Jumper Cables
Once the dead vehicle’s engine is running, remove the jumper cables in the reverse order that they were attached:
- Disconnect the negative (black) jumper cable from the metal surface on the dead vehicle’s engine or frame.
- Disconnect the negative (black) jumper cable from the negative terminal of the donor vehicle’s battery.
- Disconnect the positive (red) jumper cable from the positive terminal of the donor vehicle’s battery.
- Disconnect the positive (red) jumper cable from the positive terminal of the dead battery.

Frequently Asked Questions: How to Jump Your Car Battery
What are the safety precautions I should take when jump-starting a car?
When jump-starting a car, make sure to set the parking brake on both vehicles and put them in neutral or park gear. Turn off the engine, lights, and any accessories in both cars to prevent a surge of power. Also, ensure the vehicles are not touching each other and the batteries are not damaged. Wear protective gloves and safety glasses, and never lean over the batteries while jump-starting.
What type of jumper cables do I need to jump-start a car?
You’ll need a set of jumper cables that are rated for your vehicle’s battery voltage. Most cars use 12-volt batteries, so you’ll need 12-volt jumper cables. The cables should be in good condition, with no signs of wear or damage. It’s also a good idea to purchase cables that are the correct gauge (thickness) for your vehicle’s battery size.

How do I know which battery terminal is positive and which is negative?
The positive terminal is usually marked with a “+” sign or a red color, while the negative terminal is marked with a “-” sign or a black color. You can also consult your vehicle’s owner’s manual or look for a diagram on the battery itself to determine which terminal is which.
Can I jump-start a car with a dead battery if it has an automatic transmission?
Yes, you can jump-start a car with an automatic transmission, but you’ll need to take some extra precautions. Make sure the parking brake is set and the transmission is in park. If the car has a shift interlock, you may need to press the brake pedal and shift into park before attempting to start the engine. Consult your owner’s manual for specific instructions.
How long does it take to charge a dead car battery after jump-starting?
The time it takes to charge a dead car battery after jump-starting depends on the age and condition of the battery, as well as the capacity of the alternator. If the battery is relatively new and in good condition, it may charge quickly, within 30 minutes to an hour. However, if the battery is old or damaged, it may take several hours or even days to fully charge. It’s a good idea to have the battery tested and replaced if necessary to avoid future problems.
