The forced equalized charging test automatically stops in any of the following cases:
● The test duration reaches the forced equalized charging protection time (12–24 h, 18 h
by default).
● The UPS generates a battery overtemperature, overvoltage, or overcurrent alarm.
● An alarm is generated.

7.2.2.2 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
Settings on the LCD and verify that the value of Installation time has been
changed based on the actual situation.
● The UPS works in normal mode with a load rate uctuation less than 10%.
● The UPS does not generate any 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 UPS does not communicate with SmartLi 3.0, batteries are managed as
lead-acid batteries by default. Because the battery capacity is set to the
maximum value on the UPS UI, the battery capacity displayed on the
monitoring UI of the SmartLi should be used during a shallow discharge test.
Otherwise, batteries may be completely discharged.
Automatic Shallow Discharge Test
Step 1 On the home screen of the LCD, choose System Info > Settings > Battery
Settings and set Sched. shallow dis. test to Enable.
Step 2 Set Sched. shallow dis. test time and Sched. shallow dis. test interval as
required. After setting is complete, the system will perform an automatic shallow
discharge test based on the settings.
----End
Manual Shallow Discharge Test
Step 1 On the home screen of the LCD, choose System Info > Maintenance > Battery
Maint.
Step 2 Tap Start on the right of Shallow Dis. Test to start a shallow discharge test.
