What is the method for jump-starting a car battery?
2 Answers
First, locate the batteries of both vehicles and ensure the rescue vehicle is turned off. Connect the positive terminals of both vehicle batteries with jumper cables. After connecting, attach one end to the negative terminal of the rescue vehicle's battery and the other end to the engine block of the vehicle being rescued. After confirming the jumper cables are properly connected, start the rescue vehicle first, then start the vehicle being rescued. Once the rescued vehicle starts successfully, the jumper cables can be removed.
I've been driving for many years and have jump-started cars several times in emergencies. The method is simple but requires caution. First, park a car with a good battery nearby, not too close or too far, and make sure both engines are off. Get a set of jumper cables—one pair of red clamps and one pair of black clamps. Step 1: Connect one red clamp to the positive terminal (marked with a plus sign) of the dead battery, then connect the other red clamp to the positive terminal of the good battery. Step 2: First, connect one black clamp to the negative terminal (marked with a minus sign) of the good battery, then connect the other black clamp to a clean, unpainted metal part of the dead car’s engine block or chassis—never directly to the dead battery’s negative terminal to avoid spark hazards. Once connected, start the car with the good battery and let it run for three to five minutes to charge. Finally, try starting the dead car. Once successful, don’t remove the cables randomly: first disconnect the black clamp from the dead car, then the black clamp from the good car, followed by the red clamp from the good car, and finally the red clamp from the dead car. I always check my battery terminals for corrosion and clean them promptly to avoid issues.
