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.

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 C20 (A).

Cycle application
Charge method: 2.45V/cell with limited current of 0.25 C20 (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.
Fast charge
Increasing the charge voltage to 2.40V per cell can reduce recharge time and it is possible,
depending on the depth of discharge, to half the recharge time. Under these conditions,
however, the charge must be monitored and must be terminated when the charge current
remains reasonably steady for 3 hours after the voltage limit has been reached. At the
beginning of charge the current must be limited to 0.3C20 (A)
Ripple current
The ripple content of the charging current affects the life of the battery. It is recommended to
limit the continuous Ripple current to 0.05C20 (in amperes) as recommended value (never
exceed 0.1C20). Transient and other ripple type Voltage excursions can be accommodated
provided that, with the battery disconnected, the system peak to peak voltage including
regulation limits falls within 2.5% of the recommended float voltage of the battery.
Battery Calculations
Floating applications
A battery application is characterized by:
A voltage which must be held within certain limits;
A power level which must be delivered;
A set capacity to maintain the load in terms of time.
By the use of these three parameters, calculations can be affected as follows:
A situation requires: a maximum voltage of 490 volts a minimum voltage of 378 volts;
The ambient temperature is 25℃;
The float voltage is to be 2.27V per cell.

Preliminary calculation:
The maximum number of cells: 490V/2.27V=216 cells;
The minimum voltage per cell at the end of discharge: 378/216=1.75V.
Case1: discharge with a surge at the end of discharge
The surge power is to be 50kW for 10 minutes, followed by 10kW for 2 hours.
Discharge current:
During the surge:50000W/378V=132 amps, and then:10000W/378V=26 amps
Determining the cell required for the current required:
Current flow during surge: (132Ax10min)/60min=22Ah
Current flow for 4 hour:26Ax2h-52Ah
Total capacity drawn:22Ah+52Ah=74Ah
Equivalent discharge time at 26 amps to supply 74Ah:74/26=2.8hours
From the table of performance characteristics, expressed in terms of the discharge current in
amps for 1.75V end voltage, the cell to give a current of 26 amps for 2.8 hours is the SP12-100
Conclusion:
In this example, it is the total number of Ah required which determine the battery to be used, i.e.
216 cells/36 batteries of type SP12-100.
Case2: discharge with a surge at the end of discharge (here again, it is the surge which
dictates the battery to be used).
The continuous power is to be 10kW for one hour, followed by a surge of 50kW for 20 minutes.
Discharge current:
During the surge: 50000W/378V=132 amps
Before the surge: 10000W/378V=26 amps
Capacity drawn in 1 hour: 26Ax1h=26Ah
Capacity drawn during surge (20 min)(132 ampsx20min)/60min=43.5Ah
Total capacity drawn: 69.5Ah
Equivalent discharge time at 360 amps to supply 26Ah (69.5/132)x60min-32min
From the table of performance characteristics, expressed in terms of the discharge current in
amps for 1.75V end voltage, the cell to give a current of 132 amps for 32 minutes is the
SP12-150. The battery to be used will consist of 216 cells/36 batteries of type SP12-150.

Accidental deep discharge
This may involve discharge of the battery into indicator lamps, a lower load on the battery than
that Initially planned, a failure of the charging system, a discharged battery not recharged
immediately, etc…
On a fully discharge battery:
All of the sulphuric acid has been consumed, and the electrolyte is now nearly water.
Sulphation of the electrolyte is now nearly water. Sulphation of the plates is at a maximum,
thus increasing greatly the internal resistance of the battery. The aqueous solution in which the
battery now finds itself can give rise to the development of lead dendrites on the separator
during recharging, and this may cause the cell to short-circuit internally.
Important note:
This type of deep discharge will still result in the premature deterioration of the battery, and a
significant Effect on its life expectancy.
Effect of temperature on capacity
Temperature affects capacity of batteries. The following formula gives the correction factors
according to temperature, where the reference temperature is 25 ℃
In formula:
T---Discharge temperature
CT---Capacity at temperature of T
k---Temperature coefficient;
k=0.006/℃at C10 discharge;
k=0.008/℃at C3discharge;
k=0.01/℃at C1discharge.
