Removing the positive terminal of the car battery first is very risky. Doing so can cause an electrical short circuit if the tool used to remove it touches the metal parts of the car, which increases the chance of sparks and may ignite the gas from the battery.
In addition, removing it in the wrong south korea mobile database can also damage the car's electrical components, including electronic modules and computers that are sensitive to damage.

A short circuit may occur.
The biggest risk when removing the positive terminal first is that a dangerous short circuit can occur . If a metal tool touches both the positive terminal and the metal part of the vehicle that is grounded at the same time, it will cause a direct current to flow through it.
The result is that sparks may occur, electrical components may be damaged, and even the battery may explode because the hydrogen gas is flammable.
To prevent these dangers, we must always remove the negative terminal first.
Increase the chance of sparks
When the positive terminal is disconnected first, the risk of dangerous sparks increases greatly, especially if the wrench or other metal tool accidentally touches the car body or grounded engine parts.
