6.3.2.1 Shallow Discharge Test

Automatic Shallow Discharge Test
Before performing a shallow discharge test, ensure that:
● The UPS is working in normal mode; float charging or hibernation has lasted
● The UPS has generated no battery overtemperature, overvoltage, or overcurrent
● The mains, batteries, charger, and discharger are normal. No overload alarm is
● The SmartLi has generated no alarms related to lithium batteries.

NO TE
The capacity test automatically stops in any of the following cases:
● The battery discharge voltage reaches the EOD voltage plus 0.01 V.
● The load fluctuation exceeds 10%.
● A fault alarm is generated.
When the battery discharge voltage reaches the EOD voltage plus 0.01 V, the test is
complete. The test data is obtained from the capacity test. Based on monthly capacity test
data, select the test data obtained from a capacity test that has the maximum discharge
capacity as the current-month test data. Save the test data obtained from the latest 36
tests.
