5.6.1.3 Performing a Capacity Test
Context
Before performing a capacity test, ensure that:
The UPS is working in normal mode; float charging or hibernation has lasted for 2 hours
after the SOC reaches 100%; the load rate fluctuation is 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.
Procedure
Step 1

Figure 5-11
Starting a capacity test
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%.
An 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.
