The battery can be recovered after the car has been parked for 4 months. If the battery is relatively new or well maintained, the car can be recovered well after it has been parked for 4 months. But if the battery has been used for several years, and the owner has not maintained the battery properly, it will be difficult to restore the battery to the previous state, and the effective capacity of the battery will drop a lot.

1. Pulse voltage repair method
The battery is activated and repaired by instantaneous high voltage. The pulse voltage is relatively high, so the time to repair the battery is relatively short. When using pulse voltage, the voltage cannot be adjusted too high. When the pulse voltage value is too large, the battery will be extremely damaged. The board will be severely damaged, and the suitable voltage is in the range of 60 to 300 volts;
2,repair instrument repair method
First use the charger to activate the battery. If it cannot be charged, you need to use the high resistance of the repair instrument. The high resistance can increase the voltage of the battery. When the voltage of the battery is greater than or equal to 10v, the battery can be restored.successcharging;
3.Full charge and full discharge repair method
Let the battery be fully charged first, and then discharge all the electricity from the battery. This method can better repair the damaged battery and increase the capacity of the battery. The disadvantage is that it cannot be used frequently, and it is more appropriate to use it every 3 months.
If the vehicle is parked for a long time, when starting for the first time, it is necessary to let the vehicle run at idle speed for about 5 to 10 minutes, so that the battery is not easy to run out of power. When using the vehicle normally, you can't wait until the battery is completely dead before charging, so the service life of the battery will be greatly shortened.
