Although the car is indeed a very convenient means of transportation, but who can guarantee that you will use the car frequently, you may sometimes have to put your car away after a long trip. Therefore, at this time, we'd better disconnect the negative pole of the car battery, otherwise there is a possibility of power loss. So, how do you disconnect the negative pole of a car battery? Today we will give you a tutorial on how to disconnect the negative pole of a car battery.

1. First open the two fixing buttons of the thermal insulation wool, lift up the two red and black insulation covers on the positive and negative terminals, and then find the fastening nut of the negative electrode of the battery.
2. Then use a wrench to unscrew the fastening nut of the negative pole, and then slowly pry the fastening block with a flat-blade screwdriver. At this time, just pull out the negative pole connector.
But when we dismantle, we must follow the order of "negative first, then positive" (the opposite of the installation order). Why do we say that. Because when the negative pole is not removed, the car circuit is still in a loop state. So when removing the positive pole (the negative pole is still connected), if you accidentally touch the car metal by mistake, it is equivalent to connecting the positive and negative poles of the battery together. Not only will it cause a short circuit in the car battery, but in severe cases, it may also cause "fire", so you must be careful when removing it.
