Expected Result
The settings of battery
management parameters meet
the requirements in the user
manual.

 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.
1. Each battery terminal is
connected reliably. (When
battery strings are powered
off, check the reliability of
each terminal in the order

6 Routine Maintenance
Troubleshooting
Set parameters correctly.
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 the alarm list).
2. If the fault persists, contact
Huawei technical support.
Troubleshooting
1. Locate the cause when an
exception is identified.
2. If the fault persists, contact
Huawei technical support.
1. Rectify any abnormal
