That dreaded clicking sound when you turn the key is a universal sign of car trouble. A dead battery can happen to anyone, often at the most inconvenient times. But before you call for an expensive tow, know that you can often get back on the road in just a few minutes with a simple tool: a set of jumper cables. Knowing how to use jumper cables to jumpstart a car is an essential skill for every driver.
Gathering Your Gear and Preparing for the Jump
First, you will need a set of working jumper cables and a vehicle with a good battery to serve as the booster car. Park the booster car close to the disabled vehicle, so the cables can reach both batteries, but ensure the cars are not touching. Turn off both engines, set the parking brakes, and pop the hoods. It is also a smart safety practice to put on a pair of safety glasses if you have them.
The Step-by-Step Guide on How to Use Jumper Cables to Jumpstart a Car
With everything in position, you are ready to make the connections. Follow this order carefully to avoid sparks and ensure a safe jumpstart.
1. Connect one red clamp to the positive (+) terminal of the dead battery.
2. Connect the other red clamp to the positive (+) terminal of the good battery.
3. Connect one black clamp to the negative (-) terminal of the good battery.
4. Attach the final black clamp to an unpainted metal surface on the dead car’s engine block or chassis. This is your ground connection.
Bringing Your Car Back to Life
Start the engine of the booster car and let it run for a few minutes. Then, try to start the car with the dead battery. If it starts, great! Do not turn it off. Carefully disconnect the jumper cables in the reverse order you connected them: black from the grounded metal, black from the booster car, red from the booster car, and finally, red from the once-dead car.
Staying Safe and Avoiding Common Mistakes
Safety is paramount. Always double-check that the clamps are securely attached to the correct terminals. Never let the red and black clamps touch each other once any clamp is connected to a battery. If the car does not start after a few tries, the issue might be more than just the battery, and it is time to call a professional.
With the cables stored away, keep your recently jumped car running for at least 15-20 minutes to allow the alternator to recharge the battery. This simple, methodical process can quickly solve a common problem and get you safely on your way.
