6 Steps to Jump Start a Car

When your car battery is dead, it’s frustrating. No worries! Here are six easy steps to jumpstart car and get back on the road:

Park the second vehicle:

Bring the working car close to yours, but make sure they don’t touch. This CarandDriver guide advises positioning nose to nose so the jumper cables can reach both batteries.

Gather equipment:

You’ll need a set of jumper cables and both cars (one with a dead battery and one with a live battery). Consider wearing rubber gloves and safety glasses for extra protection.

Locate the battery terminals:

Find the positive (+) and negative (-) terminals in both cars. They are usually marked with red and black colors, respectively.

Connect the jumper cables:

Start by attaching the red clamp to the dead battery’s positive terminal. Then, connect the other red clamp to the positive terminal post of the live car battery.

Next, attach the black clamp to the working battery’s negative terminal. Lastly, connect the remaining black clamp to an unpainted metal surface on the dead car engine – it helps to ensure a safe connection.

Jump-start the car:

Start the car engine of the working car and let the engine run for several minutes. This will charge the dead battery. After waiting, try starting your car. If it starts, let it idle for at least 15 minutes to allow the battery to charge further.

Disconnect the cables:

Carefully remove the jumper cables in reverse order once your car is running. First, remove the black clamp from the dead car’s engine, then the black clamp from the live battery, the red clamp from the live battery, and finally, the red clamp from the dead battery.

Now, your car should be running smoothly! Remember to drive it for at least 15 minutes (or even 30 minutes) to allow the battery to recharge fully. Should the problem persist, consult a mechanic.

Safety Precautions

Check the Owner’s Manual

Before attempting to jump-start your car, YourMechanic suggested always referring to your owner’s manual for specific safety guidelines. Following the manufacturer’s instructions is important to avoid any hazards or damage to your vehicle.

Avoid Battery Acid

During the jump-start process, be cautious of potential battery acid leaks. Wear safety goggles and rubber gloves to protect your eyes and hands from corrosive battery acid. Never lean over the battery while jump-starting.

Inspect Cables and Terminals

Before connecting the jumper cables, inspect them for damage or corrosion. Damaged battery cables can pose a safety risk, so replace them if necessary.

Additionally, ensure the battery terminal areas are free of corrosion. Clean any visible debris to establish a secure connection when jump-starting your car.

Choosing the Right Equipment

Jumper Cables

When jump-starting a car, always use jumper cables in good condition. Visit an auto parts store where you can find quality cables. Please ensure they’re thick and have strong clamps for a secure connection.

Portable Jump Starters

A portable car jump starter might be more convenient than jumper cables. Look for one with at least a 2000A peak current and a 20000mAh capacity. This ensures it’s powerful enough to jump-start your car and can charge USB devices.

Preparing the Vehicles

Position the Vehicles

Park your vehicle and the one with a good car battery nose to nose, but without touching. Ensure the jumper cables will reach both vehicles.

Engage the Parking Brake

Apply the parking brake on both vehicles to prevent any movement.

Turn Off Headlights and Electrical Systems

Switch off your headlights, and make sure the ignition switch, engine, and all electrical systems are off in both vehicles to avoid damage.

Attaching the Jumper Cables

Connect the Positive Clamps

First, locate the positive terminal on your car’s battery, usually marked with a “+” sign. Grab the red clamp from the jumper cables and attach it to the dead battery’s positive terminal. Next, connect the other red clamp to the positive terminal post of the good battery.

Connect the Negative Clamps

Now, it’s time for the black clamps. Attach one black cable clamp to the good battery’s negative terminal (“-“).

Secure the Ground

Finally, connect the other black clamp to an unpainted metal surface on your car’s engine block, away from the battery. This is your grounding point to reduce the risk of sparks and ensure a safe jump start.

Jump-Starting the Vehicle

Start the Booster Car

First, park the booster car close to, but not touching, your car with the dead battery. Ensure both engines are off, open the hoods and locate the batteries.

Attempt to Start the Dead Car

Find both the positive and negative cables. Connect the positive cables to the positive terminals of both batteries. Attach the negative cable to the booster car’s negative terminal and the dead car’s engine block.

Now, start the booster car’s engine and rev the engine slightly. Wait a minute, and then attempt to start your car with the dead battery.

Disconnecting the Cables in Reverse Order

If your car starts successfully, disconnect the cables in reverse order, starting with the negative cable connected to your engine block, and thank your friend for their help. Drive your car to recharge the battery and double-check it’s not a sign of a more serious issue.

Post Jump-Start Tips

Check the Alternator

After jump-starting your car, let it idle for several minutes. This allows the alternator to recharge the battery. If your car stalls shortly after, the alternator may be faulty.

Charge the Battery

Connect your battery to a battery charger when possible. This ensures a proper charge and reduces strain on your alternator.

Seek Professional Help if Needed

If jump-starting fails or issues persist, contact a mechanic or roadside assistance. Remember, it’s better to be safe than stranded!

Dealing with Electric and Hybrid Vehicles

Locate the Battery

In an electric vehicle (EV) or hybrid car, first locate the 12-volt battery. Remember that EVs have two batteries, but only the 12-volt one needs a jump-start.

Follow the Manufacturer’s Instructions

Always consult your car’s manual for specific instructions. Remember to disconnect your EV from the charger before jump-starting the battery.

When to Call for Assistance

If you need clarification on the process or your car’s battery location, feel free to call for professional help. Safety should be your top priority when dealing with electric and hybrid vehicles.

Troubleshooting Common Issues

Weak or Dead Battery

A dead battery is often the cause of a car not starting. Check for any corrosion on the battery terminal or connectors. Use baking soda and water to clean them if needed.

You may have a weak battery if your car still won’t start after a jump. In this case, consider replacing the battery or testing it to ensure it’s properly functioning.

Electrical System Problems

Your car’s electrical system can also cause issues when trying to jump-start the vehicle. Listen for clicking or grinding sounds, as these may indicate a problem with your starter. Ensure all accessories like headlights and radios are turned off before attempting to jumpstart car.

Consider Replacing the Battery

If you’ve tried troubleshooting and still can’t start your car, investing in a new battery may be time.

Keep a good quality jumper cable in your car for emergencies, and maintain it for optimal performance.
