How to Jump Start a Car?

Here is the correct method for connecting jumper cables to a car: 1. Ensure the battery of the vehicle providing the jump has sufficient charge. 2. Check the voltage of the dead car's battery to ensure it matches the voltage of the rescue vehicle's battery. 3. Position the two cars close enough for the cables to connect, and inspect both car batteries for any leaks, cracks, or damage. 4. Attach the red cable clamp to the positive terminal of the dead car's battery, and the other clamp to the positive terminal of the rescue car's battery. 5. Attach the black cable clamp to the negative terminal of the dead car's battery, and the other clamp to the negative terminal of the rescue car's battery. Additional information on jump-starting a car: 1. When connecting the negative cable to the dead car, try attaching it to a metal part of the engine. This improves the starter's current circuit contact, making it easier to start. 2. Ensure every connection point is securely fastened to avoid poor contact, which may prevent a successful start. 3. Avoid letting the positive and negative terminals of the battery touch each other, as this can create intense sparks and pose a danger.
Having driven for many years, I've witnessed numerous jump-start scenes, and the operation is truly straightforward. First, position a helper car with a working battery nearby but not too close, and turn off its engine for standby. Take the thick cables and clearly identify the colors: the red clamp connects to the positive terminal (the one with the plus sign) of the helper car's battery, then the other red clamp attaches to the positive terminal of the dead car. At this point, don't rush to connect the negative; use the black clamp to connect to the helper car's battery's negative terminal or directly clamp it onto a clean metal part of the engine (to prevent sparks and gas). Then, start the helper car's engine, gently press the accelerator to let the alternator run, and wait quietly for two to three minutes to charge. Next, try starting the dead car—it should fire right up. Once successful, remove the clamps in reverse order: first the black clamp, then the red one. Afterward, it's best to drive around for a bit to ensure the voltage stabilizes; don't shut off the engine immediately. This method works in parking lots and roadside situations, so always keep a cable toolkit handy to avoid being stranded. Remember to regularly check the battery's aging condition to prevent last-minute surprises.
I often jump-start cars and know the risks; a single mistake can cause injury or fire. Recently, I saw a friend skip a step and nearly cause a fire, so I immediately reminded him that safety comes first. First, wear insulated gloves, park the car securely with the handbrake engaged, and keep the two vehicles half a meter apart to avoid contact. Use jumper cables with clear red (positive) and black (negative) clamps: attach the red clamp to the positive terminal of the first car, then connect it to the positive terminal of the second car without hesitation. Attach the black clamp first to an unpainted metal part of the engine on the working car—avoid grounding it to prevent sparks—and remove it in reverse order (black first, then red) when done. After starting the working car, rev the engine for 3-5 minutes to charge the battery, then start the second car. Don’t rush off after success—check for sparks and drive around for 10+ minutes to stabilize the charge. Beginners should read the manual or call roadside assistance; safety outweighs minor hassles.
I just learned how to jump-start a car last month, and as a beginner, there's nothing to fear. I asked my neighbor to help by parking his car on the roadside, and he taught me the steps: Identify the red and black clamps on the cables, first connect the red clamp to the positive terminal of his car's battery (marked with a plus sign), then connect it to my car's positive terminal without making a wrong connection. Next, attach the black clamp to a metal part of his engine, avoiding direct connection to the battery's negative terminal. He started his car and revved the engine while I waited a few minutes, then I turned the ignition and my car started. Finally, the order for removing the cables: take off the black clamp first, then the red one. Afterward, he had me drive a short distance to ensure the voltage was stable. It's simple and easy to learn—keeping a set of jumper cables in the car gives peace of mind on the road.
