The wheat combine harvester has a short use time and a long idle time. Therefore, the storage of the battery is crucial. Two storage methods are now introduced:
Wet method. Wet storage method can be used for short-term use without batteries. The method is: the battery is fully charged, the specific gravity of the electrolyte and the liquid level are all up to the specified value, the liquid cover is tightened, the appearance is wiped clean, and the storage is in a ventilated and dry room. The electrolyte specific gravity or cell voltage should be checked regularly during the storage period. If the stored electricity is reduced by 25%, it should be recharged immediately. Fully charge before use.
Dry method. The battery with a long period of inactivity is dry. The method is: after the battery is fully charged, the battery is completely discharged at a discharge rate of 20 hours, the electrolyte is poured out, and the distilled water is added to the water for several times to be acid-free, and the water is drained, and then the liquid-filled lid is sealed and stored. When re-enabling, first charge with a new battery.
