(12–24 h, 18 h by default).
The UPS generates a battery overtemperature, overvoltage, or overcurrent alarm.
An alarm is generated.

5.6.2 Shallow Discharge Test
Before performing a shallow discharge test, ensure that:
The UPS works in normal mode with a load ratio fluctuation less than 10%.
The UPS generates no battery overtemperature, overvoltage, or overcurrent alarm. No
generator is connected to the UPS.
The mains, batteries, charger, and discharger are normal. No overload alarm is generated.
If the battery strings of two power units are shared, you only need to perform the shallow
discharge test for one power unit to complete all battery tests. If the battery strings are not
shared, you need to perform the shallow discharge charging test on the LCD of both power
units to complete all battery tests.
