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 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 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.

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 Nominal
capacity. The discharge over 60% DOD is deep discharge and would shorten the service life.
Under the temperature of -25℃, discharge over 60% DOD is prohibited, except protective
measure is adopted such as raising temperature.
Temperature
The operation temperature range is -25℃~60℃. All the performance data is measured at ambient
temperature of 25℃.The optimal temperature is 25℃±5℃, over high temperature would shorten
the service life and over low temperature would lower the capacity available. The highest
acceptable temperature is 60℃.

Floating Charge and Equalizing charge
Floating charge
Floating operation is the best operation condition for battery. In floating operation, the battery
keep fully charged state, under this condition, battery could reach the longest service life.
Under the temperature of 25℃, recommended floating charge voltage setting value is 2.25V/
cell.
Operation and maintenance
15

In such method, it take about 24~36h for battery fully charged. For achieving better
performance, the floating charge voltage should be suitable adjusted according to ambient
temperature, temperature compensation coefficient is -3.5mV/℃/cell, for details please refer to
Table 3-1.

Equalizing charge
Equalizing charge or supplementary charge is needed in the following cases:
After finish installation, before the battery system is put into operation, the battery bank
should be supplementary charged.
The battery is out of work beyond 6 months.
Running in full-floating operation for a long term, but not discharge under more than
40%C10 capacity, the batteries need an equalizing charge regularly and the equalizing
charge cycle are 6 months to one year.
Recommended charge method as follows:
2.35V/cell with limited current of 0.15 C10(A), charge for 8~12 hours (non-continuous
charge is allowed)
Charge voltage shall be adjusted according to the ambient temperature, temperature
compensation coefficient is ±3.5mV/cell/℃, for details please refer to table 3-2.

Operation and maintenance

After equalizing charge, for batteries with voltage lower than 2.18V/cell, we should make the
battery discharged in 0.1C10 A for 4-6 hours, and then charge the battery with constant voltage
of 2.35V / cell and limited current of 0.15C10 A.
Recharge
Recharge the battery immediately after discharge according to the below method:
Charge the battery with constant current of no more than 0.2C10(A), until the battery voltage rises
to 2.33~2.37V/cell, then change to constant voltage charge of 2.33~2.37V/cell until the charge
completed. Any of the following two items can be regarded as the fully charged symbol.
Refer to the required time as table 3-3.
In constant voltage case, the charge current keep unchanged for 3 hours in the final stage of
charge.
Charge voltage shall be adjusted according to the ambient temperature, temperature
compensation coefficient is ±3.5mV/℃/ cell.

Storage
The battery should be stored in clean and dry environment .
Storage time: battery is ex-work in fully charged, storage time should be limited, for ensuring
battery performance, storage time please do not exceed following time:
Under 25℃, six months
Under 30℃, three months
Under 40℃, six weeks
The battery refreshening charge method during the storage is: charge battery with 2.35V/cell for 8
to 12 hours.
It is necessary to limit the current, and the optimum limiting value is within 0.2C10 ( A ) .
Testing of the open circuit with the storage battery can decide whether it shall be refreshening
charged. If the voltage drops to 2.10V/cell, the battery shall be refreshening charged in time.
Improper maintenance will shorten the battery service life or decrease the service performance.
Installation
Batteries integrated in equipment should be compliance with the installation instructions, Battery
which is separately installed on rack and cabinets should be connected by bolts to the foundation.
Battery racks or cabinets should be properly installed according to instructions.
Connection
Before connecting, make an overall check of all the batteries and connectors to see whether there
is hardware damage or manufacturing defects, and make sure the right polarity.
The charge equipment are in cut-off state and without loads, then connect the positive and
negative terminals to chargers.
During the installation and transit of the battery, use insulted tools, gloves, aprons and safety
glasses, avoiding battery is impacted, do not twist connecting terminals and safety valve in transit.
Placing tools and conductive articles on the battery is strictly prohibited.
Dusty connecting terminal or loose connection will cause battery sparkle, so please keep the
connecting terminals clean and tighten the connectors as per required torque value, but please do
not cause torsional stress to terminals.
