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

[DelAlexandra]

If the one-button start car battery is dead, you can jump-start it using another vehicle or an external power source. The specific handling methods are introduced as follows: Jump-starting with another vehicle: When jump-starting a car, you need to use 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 and 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. Then, take out the black negative jumper cable and 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. During the connection process, avoid letting the cables touch any metal parts of the car body to prevent a short circuit. Jump-starting with an external power source: After connecting both the positive and negative cables correctly, you can start the vehicle. Once the car starts successfully, remove the jumper cables carefully, avoiding contact with the metal body or other components. Then, let the engine idle or drive for more than half an hour to allow the engine to recharge the car's battery.
