Charge voltage of
battery string
N/A
Equalized
charging
voltage: 2.35
V/cell ± 1% x
number of
battery cells.
Float charging

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
cable diameter
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.
