Battery string charge
voltage
● Equalized charging
voltage: (2.35 V/cell
±1%) x number of
battery cells
● Float charging
voltage: (2.25 V/cell
±1%) x number of
battery cells
1. If the voltage drop
between the
battery string
output terminals
and the battery
input terminals at
the UPS side is
greater than 1% of
the battery string
voltage, check
whether the cable
between the
battery string and
the UPS is
excessively long, or
the cross-sectional
area of the cable is
excessively small.
2. Check whether the
equalized charging
voltage and float
charging voltage
are correctly set for
the UPS.
3. If the fault persists,
contact Huawei
technical support.
Battery management
parameter settings
Check that the
settings of battery
management
parameters meet the
requirements in the
user manual.
Set parameters
correctly.
Battery bolts
The location of the
signs marked on
battery terminal bolts
indicating tight
connections does not
change.
Take photos from
multiple angles and
contact Huawei
technical support.
Cables between
batteries
No cable deteriorates
and the insulation
layer does not crack.
Replace the faulty
cable.
