Operating Instruction and Guidelines

1. Discharge
End voltage with different discharge rate must be
less than the specified value. Charge the battery
as soon as possible after discharge.
In order to extend the service life, the depth of
discharge should be less than 60% of the rated
capacity. The discharge over 60% DOD is deep
discharge and would shorten the service life.
2. Temperature
The operation temperature range is -20℃
--55℃. .All the performance data is measured at
ambient temperature of 20℃. The optimal
temperature is 20 ±5 , extreme high
temperature would shorten the service life and
very low temperature would lower the capacity
available. The highest acceptable temperature is
55℃.
3. Floating charge and Equalization Charge
3.1 Floating charging operation is optimal for gel
battery, battery has been in full charge ensuring
battery maximum service life. The recommended
battery floating charge voltage is 2.24 volts/cell at
20℃. The recharge time is about 24 to 36 hour.
Floating charge voltage shall be adjusted
according to the ambient temperature, and
temperature compensate coefficient for battery is
-3.5mV//cell, the specifications is expressed by
the following table.

3.2 The batteries need an equalization charge or
supplemental charge in the following
conditions:
Supplemental charge battery after the
installation of battery system and before the
operation.
The batteries are on shelf for six months.
Floating operation for a long time or not
discharge 40% C
plus, the batteries need
20
an equalization charge regularly and the
equalizing charge cycle are 6 months to one
year.
We recommend the below method for equalizing
charge or supplemental charge:
Charge with 2.35Vpc and limited current 0.15C(A)
for 8 to 12 hours (non continuous charging is
allowed).
Charge voltage shall be adjusted according to the
ambient temperature, and temperaturec
ompensate coefficient for battery is -3.5mV//cell,
the specifications is expressed by the following
table.
