If the car owner is faced with removing the battery from the vehicle for the first time, the main question that arises during this procedure is the following: “Which terminal should be removed first?”.

Which terminal should be removed first when removing the battery?

Reasons for removal can be various situations: the battery is dead; the battery failed and so on. At the same time, certain rules should be clearly followed, strictly observing the sequence of actions, informs Ukr.Media.

The process itself does not pose great difficulties and does not take a lot of time. To do this, you need to have a wrench of the appropriate size and follow safety precautions.

At the same time, it is not recommended to apply force if it is not possible to remove the battery the first time.

The car battery has two contacts. One is positive, the other is negative. At the same time, the positive wire is suitable for electrical consumers, including a generator, a power supply or a starter. The negative is powered by the mass, which the body of the vehicle protrudes. It becomes a good conductor of electric current.

Before removing the battery, the driver must make sure that the devices that consume electricity in the car are turned off.

To avoid a short circuit or fire, first disconnect the negative contact (minus -, black color). To do this, the fastening nuts are unscrewed with the help of a wrench.

That way, if a situation arises in which a wrench or other metal tool touches the parts of the body, nothing will happen. However, if the positive terminal (plus +, red) was disconnected first, and there is metal contact with the body, then a short circuit will occur.

Only after both terminals have been removed in a strict sequence is it allowed remove the battery.

One rule must be remembered – when installing a new battery, the algorithm of actions is played in reverse order. That is, first a positive contact is established, and only after that a negative one.

If this is not done, not only the vehicle, but also a person will suffer from the resulting voltage.
