7.3.1.2 Performing a Shallow Discharge Test

This item allows you to partially discharge batteries. A shallow discharge test is
conducted to test the battery loop reliability and short-time discharge capacity
when the batteries have not been discharged for a long time.
Before performing a shallow discharge test, ensure that:
● If the battery has been replaced, choose System Info > Settings > Battery
● The UPS works in normal mode with a load rate fluctuation less than 10%.
● The UPS generates no battery overtemperature, overvoltage, or overcurrent
● The mains, batteries, charger, and discharger are normal. No overload alarm is
● If the UPS does not communicate with SmartLi 3.0, batteries are managed as
