1 Answers
Methods for jump starting a dead car battery: 1. Prepare jumper cables and a donor vehicle, ensuring the donor battery has the same voltage as the dead battery; 2. Connect the red cable to the positive terminals and the black cable to the negative terminals, making sure not to reverse the polarity as this may damage components. Ensure the cables are securely clamped to the battery terminals to prevent sparking during the process; 3. Start the donor vehicle, then attempt to start the dead vehicle; 4. After the dead vehicle starts, first disconnect the negative jumper cable, followed by the positive one. The battery is an essential part of a car, which can be divided into traditional lead-acid batteries and maintenance-free batteries.
