PROinformation SPB Series
Pure Lead Spiral VRLA Battery (SPB Series, referred as SPB hereafter) is a kind of new type of lead acid battery
independently developed by Jiangsu Shuangdeng Group Co., Ltd. SPB utilizes pure lead grid and special spiral structure
with very high assembly pressure and open valve pressure, which reduces water loss to a great extent. Compared with
normal lead acid battery, SPB has many merits, such as excellent high and low temperature discharge capability, high
current discharge capability, safe, fast charge acceptability. Based on different application fields, SPB has three kinds of
designs: cycle type, Internal Combustion Engine starting type and the type specially for solar cell system.
SPB is manufactured with 5 patented technologies, including 02112897.9, 03152809.0, 03221098.1, 200310112676.1
and 200510040205.3.
1. Characteristics
Superior high and low temperature performance, workable under -55~75
The condition is very tough when the battry are installed Outdoors. Normal lead acid battery can not be charged
efficiently under low temperature, and will suffer from water loss, swelling, transformation, fast grid corrosion under
high temperature; thus, the cycle life will be shortened.
Shuangdeng SPB utilizes special low temperature active material formula, and achieves 2 to 3 times of electrode
surface area compared to normal battery, which reduces the internal resistance to a great extent, and then makes
itself to be chargeable under low temperature. In case of high temperature, the grid corrosion rate is usually very
high; but for SPB, its cold-rolling pure lead grid has much higher corrosion resistance capability than normal lead alloy
grid, therefore, SPB has much longer service life. In addition, SPB can avoid severe water loss, swelling or
transformation by its cylindrical structure and 50kpa open valve pressure under high temperature, which ensure its
long service life.

Good PSOC performance
When a battery is applied in solar system, it can not be charged 100% after being discharged each time, then the
battery begins to work under partial state of charge (abbr. PSOC); after a long period, part of the active materials will
not be utilized, and lose their active capability, which leads to the failure of the batteries in a short time. However,
with grid of 0.6mm ~ 0.9mm in thickness and imported special separator, its internal resistance is only one third of
that of normal battery, and its capacity can be recovered to the common level after long period shelf life without
particular charge method.
Excellent low current charge acceptance
Shuangdeng SPB uses high pure lead, it has much less side effect than the normal battery, therefore, Shuangdeng SPB
can be charged with low current, and reach 90% charge efficiency even on cloudy or rainy days.
No free electrolyte, workable with any orientation
Shuangdeng SPB utilizes much 30% less electrolyte than normal battery; at the same time, its electrolyte is
completely absorbed in the plate and AGM separator, which results in no free electrolyte in the battery; therefore,
Shuangdeng SPB can be placed at any orientaton without leakage.
Steady high voltage output, high energy density
Due to the extremely low internal resistance, high output voltage remains steady voltage under middle and high rate
discharge.
Long service life
The cycle life is 350 under 100% DOD at C/5 discharge rate.
The design service life under floating application is 15 years.
The design service life in solar application is 10 years.
Fast chargeable, 95% state of charge can be reached in 40 minutes.
Starting type SPB can be discharged with super high discharge rate, the max. discharge rate is 18C10.
Very good consistency, can be connected serially and/or in parallel.
Shelf life is almost 2 years.

Note: The calculation method of discharge current and power for concrete type of battery:
Discharge current = rated capacity * Kc
Discharge power = rated voltage * rated capacity * Kw
E.g. calculating 5 minutes discharge current and power of 6V8Ah at final voltage 1.65V/cell,
discharge current =8Ah5.65=45.2A; discharge power = 6V8Ah4.58=219.8w.
