The new battery has not been opened for a few years

The new battery can be stored for one or two years without opening the package, but it needs to be recharged every 3 months or half a year, because even if it is not used, the battery will naturally discharge, and the self-discharge rate of good quality is low, and it can last longer The battery is stored in the battery, while the poor quality is the opposite. If the battery is not charged, the battery will be completely discharged, and then it will fail and cannot be charged.

The battery should be stored in a ventilated and dry place, and the battery is relatively cold, it needs to be stored in a warm environment with a temperature of 5-40 degrees, and do not place it near damp and heating equipment. When storing, please be careful not to store with electrolyte as much as possible. If you store with electrolyte, you need to charge it once in a while, and adjust the height and density of the liquid level, and store it after fully charged.

Generally, the charging time of the battery is relatively long, the average charging time is about 8 hours, and the charging time needs to be mastered. If the charging current is high, the battery can be fully charged soon, and the battery will be overcharged if it continues to charge, which will cause the battery to lose water and heat, which will reduce the battery's life. For some batteries with serious power loss, slow charging is required. If the charging time is not enough, the charging capacity is insufficient, which will affect the use of the car.
