12V 28ah High Rate Rechargeable Vrla Battery , Agm Separator Sealed
Deep Cycle Battery
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
Due to the perfectly sealed construction and the recombination of
the cells, the battery is almost maintenance free.
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.
Cyclic Service Life
More than 600 discharge/recharge cycles can be realized from CGB CB
batteries, dependent on the average depth of discharge.
Float Service Life
SE and CB, HR Series batteries have an expected life span of 3 to 5
float service applications.
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
Deep Discharge Recovery
The batteries recover their capacities even after repeated deep

Tips and Precaution
Heat kills batteries. Avoid installation and/or operation in close
proximity to heat
sources of any kind. While the operating temperature range is -15°C
and ideal service life will be realized when the battery is
operated in an ambient
temperature of 20°C (for cyclic service applications, a range of
5°C to 35°C is
If the battery is to be installed in an air or water tight
container, ventilation must
be provided. Batteries may generate ignitable gases which must not
contained. Because of this, batteries should not be installed near
Avoid installing the battery in an atmosphere where organic
adhesives may be present. Do not clean the battery with oils,
thinners or similar
substances. Use water only. The case and cover of the battery is
resin which may suffer damage from these chemicals.
