Capacity Test
Capacity test is a deep discharge test conducted to obtain the battery discharge performance data.
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 state of charge (SOC) reaches 100%; and the load ratio fluctuation is less than 10%.
- The UPS has generated 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.
- The SmartLi has generated no alarms related to lithium batteries.
Capacity Test
- On the home screen of the UPS LCD, choose .
- Tap Start on the right of Capacity Test to start a capacity test.
Notes for Capacity Test
- When capacity tests are complete, the system records data of the latest 36 tests. For details about how to view the test data, see Viewing Test Data.
- The capacity test automatically stops in any of the following cases:
- The lowest cell voltage reaches 2.65 V (test ends normally).
- The load ratio fluctuation exceeds 10%.
- A fault alarm is generated.
