What to Do When the One-Button Start Battery Is Dead?

[SimonFitz]

Here are the specific steps to handle a dead one-button start car battery: 1. Jump-start using another vehicle: (1) To jump-start the car, you will need jumper cables, which come in red and black. The red cable is the positive line, and the black cable is the negative line. First, take out the red positive jumper cable, connect one end to the positive terminal of your car's battery and the other end to the positive terminal of the other vehicle's battery. (2) Then, take out the black negative jumper cable, connect one end to the negative terminal of your car's battery and the other end to the negative terminal of the other vehicle's battery. (3) During the connection process, avoid letting the cables touch any metal parts of the car body to prevent a short circuit. 2. Jump-start using an external power source: After connecting the positive and negative cables correctly, start the vehicle. Once the car is successfully started, remove the jumper cables, being careful not to touch any metal parts of the car body or other components. Then, let the engine idle or drive for at least half an hour to allow the engine to recharge the car's battery.
