tidy without stains.
2. The battery terminals are
intact.
3. Batteries are free from
damage and cracks.
4. Batteries are free from acid
leakage.

Battery
operating
temperature
1. The ambient temperature
of batteries is 25±5°C.
2. The battery operating
temperature must be lower
than the ambient
temperature plus 20°C.
3. Battery charge and
discharge conditions meet
the requirements
specied
in the battery
specications.
1. Identify the cause of an
abnormal battery operating
temperature.
2. If the fault persists, contact
technical support.
Battery string
charging
voltage
● Equalized charging voltage
(2.35 V/cell±1%) x Voltage
of a single battery/2 x
Number of batteries in a
battery string
● Float charging voltage
(2.25 V/cell±1%) x Voltage
of a single battery/2 x
Number of batteries in a
battery string
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
oat charging voltage
are correctly set for the
UPS.
3. If the fault persists, contact
technical support.
