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

Chapter III: Operation and Maintenance
Security Instruction
Please read these instructions carefully in order to make correct, safe, and effective operation.
This manual provides you with very important installation and operation guidelines, which will
guarantee your equipment an optimal performance and longer service life.
For your safety, please do not open battery by yourself, only professionals shall be allowed to
open and maintain the battery ;
Due to battery be potential harmful to the environment and health, battery shall be replaced
by manufacturer’s service center. If there is need to replace and maintain, please contact
after-sale service center ;
Used battery is recyclable, and improper disposal of battery may be great harmful to the
environment and health. So used battery shall be proper disposed following relative
regulations and law or shall be returned to our company for disposal ;
Please choose the batteries of the same model for replacement, and batteries produced by
different manufacturers shall be strictly forbidden for connecting in one system.

Operation 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
Quantity of electricity battery discharge under certain condition is called battery capacity, symbol is
C, normal unit is Ampere Hour, and in short is Ah.
Battery capacity contains rated capacity and actual capacity, for rated capacity please refer to
Table1-1. Actual capacity is real quantity of electricity battery discharge under certain condition, it
is equal to discharge current multiply discharge time.
High temperature will speed up battery grid corrosion and water loss, thus greatly shorten the
battery life, when the temperature is over 25℃, the service life of the battery will be shortened by
half as the temperature increasing by 10℃. The optimal operation temperature is 25℃±5℃,
charge voltage should be adjusted according to ambient temperature.

Charge method: 2.45V/cell with limited current of 0.25 C20 (A).
Charge voltage should be adjusted according to ambient temperature, temperature
compensation coefficient is -4mV/cell/℃.
Setting charge capacity as 105-110% of discharge capacity, when the constant charge current
keep as same value for 3hrs, charge end.
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.
Operating
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.
