Regular maintenance of Shengyang battery effectively prolongs battery life

Shengyang batteries should be checked regularly after a certain period of time, such as observing whether their appearance is abnormal, measuring whether the voltage of each Shengyang batteries is average, etc. If there is no power supply for a long time, the battery will always be charged, which will make the battery's activity worse. Therefore, even without power failure, UPS needs to conduct periodic discharge tests in order to keep the battery active. Discharge test can generally be carried out once in three months. The method is that UPS is loaded - preferably more than 50%, and then the power is disconnected to make UPS in the discharge state of Shengyang batteries. The discharge duration is usually several to dozens of MS depending on the capacity of Shengyang batteries. After discharging, the power supply of the municipal power is restored and the batteries are charged continuously.
