Conduct a shallow
discharge test when the
UPS is backed up to verify
that the batteries can
discharge normally.
6 Routine Maintenance
Troubleshooting
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,
