How to Remove the Negative Terminal of a Car Battery?

[ValeriaMarie]

The method to remove the negative terminal of a car battery is: 1. Open the driver's door of the car; 2. Pull the hood release lever located on the left side of the driver's leg area; 3. Lift the car's engine hood upwards; 4. Secure the engine hood with a support rod, ensuring it is firmly propped to avoid hazards during operation; 5. Locate the battery—the black side is the negative terminal—and simply unscrew the negative terminal bolt. The functions of the battery are: 1. To power the engine starting system, ignition system, and other electrical components of the car; 2. To supply power to the car's electrical devices when the engine is off or idling at low speed; 3. To mitigate voltage surges in the electrical system and protect the car's electronic equipment.
