Our gel batteries uses German origin high purity fumed silica to
acid thixotropic Gel and fills to the batteries with vacuum to
ensure the fully
penetration of electrolyte through separators and plates pastes.

The unique construction and sealing techniques of the battery
proof operation in any position with no adverse effect to capacity
or service life.
Electrolyte Suspension System
All batteries utilize an electrolyte suspension system consisting
of a high
porosity, glass fiber material which in conjunction with plates,
totally absorb and
contain the electrolyte.
CGB batteries incorporate a built-in design that controls gas
induces recombination of more than 99% of gases generated during
Maintenance Free Operation
There is no need to check specific gravity of the electrolyte or
add water to
batteries during float service life. In fact, there is no provision
for this type of
Low Pressure Valve Regulated System..
All batteries are equipped with safety release valves, designed to
between 1.5 and 6 psi (10-40kPa) and automatically reseal. Hence,
never an excessive accumulation of gas within the battery.
Heavy Duty Grids
Heavy duty lead calcium tin alloy grids provide an extra margin of
and service life in either float or cyclic applications.
Float Service Life
GEL Series batteries have an expected life span of 5 to 8 years in
Self Discharge - Shelf Life
The self discharge rate at room temperature is approximately 3% of
capacity per month.
CGB Batteries may be operated over a broad range of ambient
