Shuangdeng battery GFM-500 2V500AH (C10) balanced charging basic requirements: a capacity test qualified, the discharge end of the double deng battery immediately received on the charging device for balanced charging (note: The positive pole of the double deng battery group is connected to the positive pole of the charging device, and the negative pole of the double deng battery group is connected to the negative pole of the charging device. It should not stay for too long, so as not to cause the double deng battery to discharge, and shorten the service life of the battery. The charging voltage is 2.35V/monomer (ambient temperature is 25℃). The temperature compensation coefficient is carried out according to the technical instructions of the product. The charging current is not more than 0.25C10. The temperature of the battery is generally maintained in the range of 5-30℃, below 5℃ or higher than 35℃ may reduce the life of the battery due to insufficient charging or overheating. If the temperature of the double deng battery is higher than 35℃, the charging current should be reduced, or the charging should be stopped, and the temperature should be reduced to a specified range for charging).
