What is the method for jump-starting a battery?

Method for jump-starting a battery: 1. Park the donor vehicle and the recipient vehicle close together, and turn off the engines and all electrical equipment of both vehicles; 2. Connect one end of the red cable to the positive terminal of the donor vehicle's battery, then connect the other end to the positive terminal of the recipient vehicle's battery; 3. Connect one end of the black cable to the negative terminal of the donor vehicle's battery, then connect the other end to the negative terminal or a metal part of the recipient vehicle's battery; 4. Start the donor vehicle and rev the engine a few times in neutral to generate higher current for charging the recipient vehicle's battery; 5. Start the recipient vehicle and let it idle for 15 to 30 minutes to allow the battery to charge sufficiently; 6. After charging, turn off both vehicles, then remove the black cable first, followed by the red cable, completing the jump-start process. It is important to note that when connecting the vehicles, always connect the positive terminals first and then the negative terminals. When disconnecting the cables, always remove the negative cable first and then the positive cable. The order must not be reversed, as this could cause a short circuit in the battery, creating a safety hazard.
I've encountered several situations where the car battery died. The method of jump-starting is actually quite simple but safety must be prioritized. First, park the two cars close to each other but don't let them touch, with both engines turned off. Then take out the red positive clamp and attach it to the positive terminal of the charged battery (usually marked with a plus sign or has a red cover). Next, connect the other end of the red clamp to the positive terminal of the dead battery. The black negative clamp should first be attached to the negative terminal of the charged battery, then connect the other end to a clean metal part of the dead car's body or engine frame - never attach it directly to the negative terminal to avoid spark explosions. Start the working car and let it idle for a few minutes to charge the battery, then try starting the dead car. If successful, let it run for a while before disconnecting the cables. This situation often occurs with aging batteries or during extreme cold when power is insufficient. Regular checks of battery age and keeping terminals clean can extend battery life and prevent frequent jump-starts.
