Vo l t a g e ( 2 V )
OPzV Series(Tubular Gel Battery)
In the later period of charging or over-charging the positive generates oxygen, and the negative
generates hydrogen. The negative plates adopts high purity Pb-Ca alloy to increase the
hydrogen overpotential and to inhibit the generation of hydrogen. OPzV battery adopts unique
GEL electrolyte technology, the Gel-forming material forms three-dimensional porous
construction which provides many small gaps (channels for oxygen recombination). During the
later period of charging, the oxygen generated by the positive reaches the negative through
these gaps and reacts with spongy Pb to generate H O which goes back to the battery. During
2
this process the battery doesn't lose any H O, Thus the battery can be well sealed and
2
maintenance free.
Step 2: The oxygen generated by the positive reaches the negative through the GEL
gaps and reacts with spongy Pb and acid to generate H O which goes back to the battery
2
system.
Step 3: Lead sulfate generated by the negative generates lead and sulfuric acid in battery
charging to join in the charging reaction.

1.Battery Structure & Plate Design
OPzV Series(Tubular Gel Battery) OPzV Series(Tubular Gel Battery)
● Positive Plate: The battery adopts tubular positive plates. The positive grids are made by die-casting technics with the
pressure of 18MPa and are cylindrical structure; more compact and offer good corrosion-resistance, an extreme high
cyclic expectancy and a long design life more than 20 years.
● Pole Sealing: Triple Seal(mechanical sealing+special sealant+epoxy glue). The first step is an O ring plus the
helical structure ensuring the battery is air-tight and does not leak; the second step adopts special sealant ensuring the
battery has no acid leakage; the third step adopts epoxy glue.
● Formation Method: Use the most advanced technology of internal formation to inject GEL once only. The production
process is more environment-friendly; the product quality is more reliable; batteries have better consistency.
● Electrolyte: GEL comprises classic quality fumed SiO2 , which is liquid sol when being injected and
the fully packed. The electrolyte finally becomes i no
flow, no leakage and stratification, and higher security.
Flooded electrolyte design, contains more electrolyte than AGM batteries ; space between plates and
separators is full of electrolyte thus means good heat capacity, good heat dissipation, overcharge resistant, stable
high and low temperature ,and avoid “thermal runaway”.
● Container:The battery container is made of high strength ABS. Container and lid are sealed together by quality
adhesives ensuring reliable sealing performance in service.

Conductance, Internal Resistance and Short Circuit Current
OPzV Series(Tubular Gel Battery) OPzV Series(Tubular Gel Battery)
The OPzV battery’s conductance and internal resistance decrease with the capacity
increasing. They are dynamic parameters instead of linear ones and change with
temperature, SOC(state of charge) and discharge state. The internal resistance is the
smallest when the battery is fully charged, while the conductance is the biggest at this
time. The values listed below are based on the same condition.(The temperature is
about 25℃.)
Notice: When measuring the conductance or resistance, deviation may happen due to the
different contact state of the pole and the testing point, or if the measuring tools sensitivity
is different or the tools are from different manufacturers. The following values are
based on the battery being fully charged and in accordance with
IEC60896-21/22, for reference only.

Match batteries into battery banks, and group the batteries of the same or similar open-circuit voltage as a
bank. The voltage difference of a single cell is recommended to be a grade.
☆
☆
Check and make sure batteries are normal, then install batteries at the predetermined location (eg a battery
rack).
☆
Do not install batteries near any heat sources (eg a transformer).
☆
Because batteries may produce flammable gas during storage, keep away from any devices with possibility
of sparks (eg a fuss) during installing.
Before connection, clean battery terminals and make them shine with metallic luster.
☆
Be careful not to short-circuit battery positive and negative terminals with conductive materials.
In multiple use, make sure batteries are connected correctly and then connect batteries to the charge
or load. The positive terminals should be connected with the positive of the charger or load,
while negative with negative. If batteries are not connected to the charger correctly, the charge will be
damaged. Make sure there is no connection error.

☆
Connect wires tightly and make sure every connection nut and bolt is screwed down. But do not overexert
to prevent damages to terminals. The recommended tightening torque is as follows.

3. Installation and Wire Connection
Use insulating tools. The metal tools (such as a wrench) should be wrapped with insulating
tape and given insulation treatment.
Connect batteries firstly and then connect battery banks to the charger or load.
When multiple battery banks are to be in parallel connection, they should be connected in series
first and then connected in parallel.
The gap between batteries should be more than 20mm to ensure good ventilation.
Apply antirust agent (such as vaseline) on battery terminals before and after connection.
When batteries are installed, measure the total voltage of battery banks and confirm it is correct,
then load power.

5. Battery Maintenance
5.1 Cleaning
☆Keep the battery appearances and operating environment clean and dry.
☆Do not cause static when cleaning batteries.
☆Clean batteries with a wet cloth. It's prohibited to use gasoline, alcohol or any other organic
solvents to clean batteries.
5.2 Inspection and Maintenance
1) Monthly Inspection
Item Content Benchmark Maintenance
The total float
charge voltage
of the battery
bank
Inspect the voltage of
the battery bank's
positive and negative
terminals with a
voltmeter
The float charge
voltage of a single
cell x battery
quantity
Adjust the deviation value
to the benchmark value
Battery
appearance
Inspect the battery case,
lid to check wether there
is leakage, blow-up, or
damage
The appearance is
normal
Please check the reason of
the unusual appearance;
and if it affects the normal
use, replace the battery
Inspect whether there is
dust or dirt
The appearance is
clean
Clean the dust and dirt with a
wet cloth
Inspect whether the
connection cables
and terminals get rusty
No rust
If there is rust, please clean
the rust, replace the rusty
connection cables, and apply
rust inhibitor
Connection
parts
Inspect whether bolts
and nuts get loose
Firm connection (see
the torque table)
Tighten the loose bolts and
nuts according to the
requested torque
Clean the battery
bank’s connection bars
and terminals
No corrosion
For slight corrosion,
disassemble the connection
bar and immerse it in water for
cleaning; for serious corrosion,
change the connection bar and
after cleaning the connecting
points with a steel brush
reconnect and tighten the new
one
Safety Valve
Shake the safety valve
gently to check whether
it is fastened securely
Firmly, no loose If the safety valve is loose,
fasten it
Check whether the
safety valve is
working: apply the
foaming liquid around
the safety valve to
observe its gas
Bubbles appear
periodically
It is abnormal if the safety
valve is in longtime closing or
opening and need to change
the safety valve (and check
the battery water loss
condition at the same time )
Switch
Cut off the AC power, and
switch to the UPS, power
cabinet or DC power
The AC power supply
switches to the
power cabinet or DC
power smoothly
UPS, Correct the possible deviation
2) Quarterly Inspection
Item Content Benchmark Maintenance
The float
charge
voltage of
each battery
Inspect the terminal
voltage of each battery
in the battery bank
The float charge
voltage with
temperature
compensation
(±50mV)
If it exceeds the benchmark
value, please discharge firstly
and then equalizing charge
and switch to float charge for
1~2 months. If it still deviates
from the benchmark value,
please contact us

Item Content Benchmark Maintenance
Verification
discharge
testing
Cut off the AC power and
discharge with load;
discharge 30%~40% of
the rated capacity of the
battery
The battery voltage
should be over
1.90V/cell when
discharge stops
If it is lower than the
benchmark value, please
discharge the battery bank
firstly and then equalizing
charge and then switch to float
charge for 1~2 months. If it
still deviates from the
benchmark value, please
contact us
