How to Jump Car with Battery Charger

Car batteries can fail for many reasons, leaving drivers stranded and frustrated. Fortunately, a battery charger can be used to jumpstart a car and get it back on the road. Here's a step-by-step guide on how to jump car with battery charger.

Preparing to Jumpstart the Car

Before attempting to jumpstart a car with a battery charger, it's important to inspect the battery and charger for any damage or defects. Check the battery for leaks, cracks, or other signs of damage. If the battery is damaged, it may not be safe to jumpstart the car and a replacement may be necessary. Make sure the battery charger is working properly and is capable of delivering the amount of power needed to jumpstart the battery.

Identifying the positive and negative terminals on the battery is also crucial. The positive terminal is usually marked with a plus sign (+) and is typically red, while the negative terminal is marked with a minus sign (-) and is usually black. It's important to avoid connecting the positive and negative clamps of the battery charger to the wrong terminals, as this can cause damage to the battery or even lead to an electrical shock.

Connecting the Battery Charger to the Car

Once you've inspected the battery and charger and identified the terminals, you're ready to connect the battery charger to the car. Place the battery charger in a safe location near the car, but not so close that it could accidentally come into contact with the battery or any other metal parts of the car.

Attach the positive clamp of the battery charger to the positive terminal of the battery. Make sure the clamp is securely attached and won't come loose during the charging process. Then, attach the negative clamp of the battery charger to a suitable grounding point on the car, such as a metal bracket or bolt. This will help prevent any electrical sparks or arcs that could damage the battery or cause a fire.

Charging the Car Battery

Once the battery charger is connected to the car, it's important to set the charger to the appropriate voltage and amperage for the car battery. Consult the owner's manual for the car or the battery charger to determine the correct settings. Most battery chargers have a "start" or "boost" mode that delivers a higher voltage and amperage to help jumpstart the battery quickly.

Start the battery charger and allow it to charge the battery for several minutes. Monitor the charger and battery to ensure that the charging process is going smoothly and that there are no signs of damage or overheating. If the charger or battery becomes too hot or starts to emit smoke or sparks, disconnect the charger immediately and seek professional help.

Starting the Car

Once the battery has been charged for several minutes, try starting the car. If the car starts, disconnect the battery charger from the car in the reverse order that you attached it. Remove the negative clamp first, then the positive clamp. If the car doesn't start, repeat the charging process for several more minutes and try again.


Jumpstarting a car with a battery charger can be a quick and easy solution to a dead battery. However, it's important to take the necessary safety precautions and follow the proper procedures to avoid causing damage to the battery or the car. Always consult the owner's manual for the car and the battery charger to ensure that you're using the correct settings and procedures. With a little bit of preparation and care, you can safely and effectively jumpstart your car and get back on the road.
