How to Jump Start a Car with Dead Battery?
2 Answers
To jump start a car with a dead battery, follow these steps: 1. Prepare two jumper cables; 2. Find a vehicle that can run normally; 3. Position the two vehicles facing each other; 4. Connect the jumper cables to the batteries, positive to positive and negative to negative; 5. Start the working vehicle first, then start the dead vehicle, and disconnect once it's running. Jump starting, also known as borrowing power, works by transferring stored electricity from one vehicle's battery to another through external equipment. Once the vehicle starts normally, the external equipment can be removed, allowing the car to recharge its battery through the jump start.
I've been driving for decades, and jump-starting a car is pretty common. Just last week, my neighbor's car battery died, and I helped him out. First, park a car with a good battery close to the dead one, turn off both engines, and pop the hoods. Use the red clamp to attach to the positive terminal (the '+' sign) of the donor car's battery, then attach the other red clamp to the positive terminal of the dead car. The black clamp goes to the negative terminal ('-' sign) of the donor car, and the other black clamp should be attached to a grounded metal part of the dead car, like the engine block—never directly to the negative terminal of the dead battery, as it can cause sparks. Then, start the donor car and let it idle for a few minutes to charge the dead battery. Next, try starting the dead car. If it starts, keep the engine running and remove the black clamp from the dead car first. Avoid touching any metal parts during the process to prevent short circuits. Afterward, it's a good idea to drive the previously dead car for a while to recharge the battery and check its lifespan, so it doesn't die again next time.
