What is the method for jump-starting a car?

[VonTheo]

Car jump-starting method is: 1. Drive the charged car next to the dead car, with the front ends facing each other and close; 2. Open the hoods of both cars and take out the jumper cables; 3. Locate the batteries of both vehicles, attach the negative clamps to the negative terminals of both car batteries, and attach the positive clamps to the positive terminals of both car batteries; 4. Start the charged car, charge for a few minutes, then start the dead car to get it running. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine is stopped or at low idle, it provides power to the car's electrical equipment; 3. When the generator's output is insufficient, it supplies power to the electrical equipment; 4. It mitigates voltage surges in the electrical system, protecting the car's electronic devices; 5. It stores excess electricity generated by the alternator.
