1. It is necessary to understand how long the UPS uninterruptible power supply can be backed up before discharging, so that when discharging, there is a preparation to prevent the discharge to the back-up time, without knowing it, causing load downtime. Cause damage to the equipment.
2. If you can see the UPS battery, first visually check whether the battery has obvious deformation and leakage.
3. If the UPS uninterruptible power supply itself has the automatic discharge function to set the time, it is recommended to let the UPS uninterruptible power supply to discharge by itself first, so that you can preliminarily judge whether the battery has the ability to discharge.
4. When discharging artificially, please always observe the drop of UPS battery voltage so as to restore the mains input at any time.
5. Discharging the UPS uninterruptible power supply does not need to completely discharge the battery capacity. It is OK to just put it to 2/3 of the rated capacity. Discharge only has the effect of activating the battery. Extend the use time of the ups battery.
6. If it is a medium and high-power UPS power supply, the general rectifier and bypass input switch are designed independently. It is recommended to turn off the rectifier switch instead of turning off the user's mains input switch to prevent uninterrupted power supply in case of battery discharge. You can immediately switch to bypass mode to work.
