Capacity Test
Issue 03 (2021-08-03)
Expected Result
The secure connection
signs on battery terminal
screws are in proper
positions.
No cable deteriorates and
the insulation layer does
not crack.
● Equalized charging
voltage: 2.35 V/cell
± 0.02 V/cell.
● Float charging voltage:
2.25 V/cell ± 0.02 V/
cell.
Conduct a shallow
discharge test when the
UPS is backed up to verify
that the batteries can
discharge normally.
Expected Result
When the UPS is backed up,
discharge a battery to the
undervoltage alarm threshold,
to refresh the capacity of the
battery.

Troubleshooting
Take photos from multiple
angles and contact Huawei
technical support.
Replace the faulty cable.
1. Check whether the
equalized charging
voltage and float
charging voltage of a
battery are normal.
2. If the charging voltage
of a battery exceeds the
specifications
requirement, perform a
complete forcible
equalized charging for
the battery, and check
again whether the
voltage is normal.
3. If the fault persists,
contact Huawei
technical support.
1. If the batteries cannot
discharge normally,
locate the fault (for
abnormal alarms, see
UPS5000 & SmartLi
the
