VRLA Technology
The electrochemical reaction of batteries in charge and discharge process is as follows:
Discharge
PbO2+2H2SO4+ Pb PbSO4+ 2H2O + PbSO
4
Charge
In the final stage of charge process, active substance in positive plate is fully transformed to lead
dioxide, but negative plate has not reached fully charged stage, the process of active substance in
negative plate transforming to spongy lead is not finished, oxygen gas generated in positive plate
reaches the negative plate through separator pores and then reacts with active substance in
negative plate, resulting depolarized state in negative plate, and restraining the generation of
hydrogen.
Principle of the oxygen reduction cycle is as follows:

Chapter III: Operation and maintenance
Safety Instructions
Please read these instructions carefully in order to ensure correct, safe and effective operation.
This manual provides you very important guidance for installation and operation, which will
guarantee your equipment with optimal performance and longer service life.
For your safety, please do not open the batteries;
As batteries contain lead which can potentially be harmful to the environment and health, and
as batteries are connected to electricity, they must be installed, maintained and replaced by
skilled personnel only.
Used batteries must be recycled and disposed properly as improper disposal of batteries is
harmful to the environment and health. Used batteries shall be properly disposed following
relative regulations and laws.
It is strictly forbidden to mix batteries with different specifications, manufacturers and
capacities.
All installations must comply with the safety regulations and norms. Read through our
Operation Guide / Safety Instructions before starting any installation work.

Operating Parameters
Ambient temperature is -15℃~45℃and the optimal operation temperature is 25℃±5℃.
Ambient humidity less than RH 92%
Altitude less than 4500m, if operation altitude more than 4500m, please make special
reminder when confirm order.
Factors Influencing Capacity
Battery capacity consists both of nominal capacity and actual capacity, for nominal capacities of
the FT series battery please refer to Table 1-1. Actual capacity is the real quantity of electricity
battery discharge under certain condition, it equals to discharge current multiplied by discharge
time, the unit is Ah.
Battery capacity is directly related to discharge current, end voltage and discharge
temperature.
Temperature Effect on Battery Capacity
Figure 3-1 describes temperature effect on battery capacity (C10). For example, if temperature
falls from 25℃to 0℃, battery capacity will be 85% of the nominal capacity, low temperature will
cause long term charge shortage, negative plates will be irreversibly sulfated and as a result the
battery cannot be used normally.
As temperature rises, battery capacity will increase to a certain point. For example, if temperature
rises from 25 ℃to 35 ℃, battery capacity will be approximately 105% of the nominal capacity.
From 35℃to 50℃, the capacity increase is very low and if temperature rises beyond 50℃, there
is no increase in battery capacity.

Charge
Floating charge
Charge method: 2.27V / cell with limited current of 0.3 C10 (A).
Charge voltage must be adjusted according to ambient temperature, temperature
compensation coefficient is -3mV / cell /℃.

Cycle application
Charge method: 2.40V / cell with limited current of 0.25 C10 (A).
Charge voltage must be adjusted according to ambient temperature, temperature
compensation coefficient is -4mV / cell /℃.
When charged capacity is about 105-110% of discharged capacity or in constant voltage case,
the charge current must be kept unchanged for 3 hours in the final stage of charge., charge is
ended.

Operation
Warning
The batteries are already charged when delivered, and are fitted with a protective cap on
each terminal. They should be unpacked with care.
Avoid short-circuiting terminals of opposite polarity, because these units are capable of
discharging at a very high current especially if the lid or the container is damaged.
Unpacking the battery
Each shipment is accompanied by a packing list
The packing list should be checked, and the Sales Department should be told immediately
of any missing items.
Setting up the battery racks
The structure should be assembled in accordance with instructions supplied with the
equipment.
Racks
Ensure that the stretchers and cross-members are correctly interlinked.
Take up any irregularity in floor surface using shims
Ensure that all frame members are correctly interlinked.
Use the adjustable feet to take up irregularities in the floor surface.
Metal racks should always be connected to the building earth in accordance with current
regulations.
Mounting in a cabinet
Ensure that the cabinet:
Is sufficiently strong to cope with the weight of the battery
Is covered with a layer of insulation
Is naturally ventilated.
Connection of cells
All connections should be insulated.
