At present, the valve-free maintenance-free battery machine room is used, the UPS DC power supply, DC screen, emergency power supply, elevator battery and other fields, VRLA batteries have uneven floating voltage, which is used by the production of batteries. The quality, quantity of the material and the amount of the material are accumulated, in particular the VRLA battery adopts a poverty-like design, and the error will affect the sulfate saturation of the battery inside, which directly affects the reincarnation of oxygen when the battery is floating. Make the booming battery excessive output, the floating voltage of the battery is different.
However, the floating voltage will tend to be uniform after the VRLA battery is running for a certain period of time. Because the amount of battery oxygen-saturated battery is poor, the saturation is slightly lowered, and the floating voltage of the battery tends to be uniform. Another battery is connected in series; poor pillar and connection strip contact; there may be uneven phenomena in three to six months. The backward battery should be measured at the time of discharge, so the backward battery should be measured in the discharge state. If the end voltage is the lowest in the continuous three-time discharge cycle, it can be sentenced to the backward battery in the group, and there is a backward battery. Battery group is balanced.
