Will the car battery be dead if the car battery is not turned on for a month? How long can the car battery be fully charged after running

I believe that many friends know that even if the car does not open, the battery will still be naturally worn out (about 1% loss per day and night). So when we go out for a long trip, we have to put our car away, even as long as a month. At this time, the question arises. Will the car battery run out if the car battery is not turned on for a month? How long can the car battery be fully charged after running out of battery.

Normally, if the car is not turned on for a month, the battery will not be dead. Of course, it is best to unplug the battery's positive and negative poles (to avoid natural power consumption of the car battery). However, for a car in a poor condition, the battery may be running out of power in about a week. But you don’t have to worry too much. As long as you drive for one to two hours, you will be able to return to normal power. If it is too serious to start the engine, it is necessary to jump start the generator to activate it.

Steps to jump start the generator:

1. First make sure that the auxiliary battery is 12 V and the negative terminal is grounded. Of course, we have to turn off all unnecessary lights and accessories to avoid electricity accidents.

2. Then follow the order shown in the figure below to connect the jumper cables. Do not reverse the positive and negative poles of the cable, otherwise it will jump out of sparks when it is connected, and we must wrap the cable and the battery tightly (full contact) to avoid flashovers during the power connection. Phenomenon.

3. Start the engine of the auxiliary battery vehicle and run the engine at a medium speed. Then start the engine of the vehicle whose battery is exhausted.

4. Finally, just disconnect the cables in the reverse order.
