Technical Features
Plate
Following our research on corrosion effect during battery life, we have improved the technology of
grid alloy, lead paste formula additive. During manufacturing process with high temperature and
high humidity this process solidify, increase the content of 4PbO·PbS4O·H2O, improving the binding
ability of active material and grid pasting, avoiding early capacity loss due to barrier layer between
active material and grid paste.
Gel electrolyte
Fumed Silic aused for Gel electrolyte ensuring even distribution inside battery and with no acid
stratification.
High quality electrolyte ensures a high level of filling gel electrolyte in box between and over the
plates and separators which give perfect heat dispersion and prevent thermal runaway caused by
water loss, and gel electorlyte protects active materials from shedding.

Technology
Working and sealing principle
In the charge and discharge process of ABT-GEL battery, it occurs to below reaction in the battery inside
Discharge
PbO2 +2H2SO4 + Pb PbSO4 + 2H2O + PbSO4
Charge
At the later stage of charging or over-charge condition, oxygen would be evolved from positive electrode
and hydrogen would be evolved from negative electrode. The negative electrode is made of high pure
lead-calcium alloy, which inhibit the hydrogen evolution. The batteries apply special gel electrolyte
technology, and the gel is with three dimensional net porous structures, and also with some tiny cracks
as gas passage. The oxygen from positive electrode get to negative through the special gel and rapidly
react with the spongy lead existing on the negative electrode and produce water. This process is called
gas recombination and no water loss during it. The battery is sealed in this way and achieves
maintenance free.
Reaction in the process
1. H2O→2H++1/2O2+2e-
2. O2+2H2SO4+2Pb=2PbSO4+2H2O
3. PbSO4+2H++2e-→Pb+H2SO4

Operating Instruction and Guidelines
1. 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 rated
capacity. The discharge over 60% DOD is deep
discharge and would shorten the service life.
2. Temperature
The operation temperature range is -20℃
--55℃. .All the performance data is measured at
ambient temperature of 20℃. The optimal
temperature is 20 ±5 , extreme high
temperature would shorten the service life and
very low temperature would lower the capacity
available. The highest acceptable temperature is
55℃.
3. Floating charge and Equalization Charge
3.1 Floating charging operation is optimal for gel
battery, battery has been in full charge ensuring
battery maximum service life. The recommended
battery floating charge voltage is 2.24 volts/cell at
20℃. The recharge time is about 24 to 36 hour.
Floating charge voltage shall be adjusted
according to the ambient temperature, and
temperature compensate coefficient for battery is
-3.5mV//cell, the specifications is expressed by
the following table.

3.2 The batteries need an equalization charge or
supplemental charge in the following
conditions:
Supplemental charge battery after the
installation of battery system and before the
operation.
The batteries are on shelf for six months.
Floating operation for a long time or not
discharge 40% C20 plus, the batteries need
an equalization charge regularly and the
equalizing charge cycle are 6 months to one
year.
We recommend the below method for equalizing
charge or supplemental charge:
Charge with 2.35Vpc and limited current 0.15C(A)
for 8 to 12 hours (non continuous charging is
allowed).
Charge voltage shall be adjusted according to the
ambient temperature, and temperaturec
ompensate coefficient for battery is -3.5mV//cell,
the specifications is expressed by the following
table.

Operating Instructions and Guidelines
5. Recharge
Battery should be recharged in time after
discharge, the recommended charge methods
are:
Charge the battery with constant current of less
than 0.2C10Auntil the battery boost voltage reach
2.33~2.37Vpc, then charge battery with the
constant voltage 2.33~2.37Vpc until the end of
charge. Charge voltage shall be adjusted along
with ambient temperature, the temperature
compensate coefficient for battery is -3.5mV/℃
/cell.
Whether the batteries are fully charged can be
decided according to any one of two standards
as follows:
Different discharge depth. Sufficient charging
time varies according to the different discharge
depth. Please note from the table below
Under constant voltage charge condition, the
charge current value maintains the same
during the last three hour when the battery
reaches the final stage of charging.

6. Storage
GEL batteries should be stored in a dry, clean,
and ventilated location. Since the batteries are
fully charged, the recommended storage time is
as follows:
6 months at ambient temperature no warmer
than 68°F (20℃)
3 months at 86°F (30℃)
6 weeks at 104°F (40℃)
The state of charge can be decided by the testing
result of open circuit voltage after storage for 24
hours at 20±5℃.
Table open circuit voltage
State of charge
Voltage (V/cell)
100%
≥2.18
80%
≥2.16
60%
≥2.12
40%
≥2.10
20%
≥2.06
The battery supplemental 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 0.2C10A .
Testing of the open circuit with the storage
battery can decide whether it shall be
supplemental charged. If the voltage drops to
2.10Vpc, the battery shall be supplemental
charged in time.
Improper maintenance will shorten the battery
service life or decrease the service performance.
13
