How to Disconnect the Battery Negative Terminal?

[Sabrina]

Disconnecting the battery negative terminal involves the following steps: 1. Open the two fastening buttons of the thermal insulation cover, lift the red and black insulation caps above the positive and negative terminals, and locate the tightening nut of the battery negative terminal. 2. Use a wrench to loosen the tightening nut of the negative terminal, then gently pry open the fastening block with a flat-head screwdriver, and directly pull out the negative terminal. During the disconnection process, it is crucial to follow the sequence of disconnecting the negative terminal first, followed by the positive terminal. Accidentally touching the car metal is equivalent to connecting the battery's positive and negative terminals, which can not only cause a short circuit in the car battery but may also lead to sparking in severe cases. It is recommended to seek professional assistance at a 4S store for disconnection.
