The power supply for the vehicle's electrical equipment depends on the battery.
It needs to be charged whenever it shows signs of depletion.
This is not a difficult task, you just need to know which terminal to remove from the battery first.
When disconnecting the battery, you must remove the negative terminal first.
This will prevent a short circuit in the event of accidental contact of a metal key with car parts connected to the negative terminal.
It is extremely important to follow this rule, because a short circuit can burn out the wiring or damage the electrical parts of the car.
The terminals should be connected in reverse order - first the positive, then the negative.
