Set parameters
correctly.

Quarterly

Tightness of bolts on
battery terminals

The location of the
signs marked on
battery terminals
indicating tight
connections does not
change.

Take photos from
multiple angles and
contact Huawei
technical support.

Quarterly

Cables between
batteries

No cable
deteriorates and the
insulation layer does
not crack.

Replace the faulty
cable.

Quarterly

Battery voltage

Equalized
charging voltage:
14.16 V ± 0.1 V



Float charging
voltage: 13.68 V
± 0.1 V

Check whether
the equalized
charging voltage
and float
charging voltage
of a battery are
normal.

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.

If the fault
persists, contact
Huawei technical
support.

Quarterly

Shallow discharge
test (recommended)

Conduct a shallow
discharge test when
the UPS is backed
up to verify that the
batteries can

Locate the cause
when an
exception is
identified.

If the fault
persists, contact
