TECHNICAL FEATURES:
Sealed Construction
The unique construction and sealing techniques of the battery guarantee leak
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.
Gas Recombination
CGB batteries incorporate a built-in design that controls gas generation and
induces recombination of more than 99% of gases generated during float or
cyclic usage.
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
maintenance.
Low Pressure Valve Regulated System..
All batteries are equipped with safety release valves, designed to operate
between 1.5 and 6 psi (10-40kPa) and automatically reseal. Hence, there is
never an excessive accumulation of gas within the battery.
Heavy Duty Grids
Heavy duty lead calcium tin alloy grids provide an extra margin of performance
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 float service
applications.
Self Discharge - Shelf Life
The self discharge rate at room temperature is approximately 3% of rated
capacity per month.
Operating Temperature
CGB Batteries may be operated over a broad range of ambient temperatures.
Deep Discharge Recovery
The batteries recover their capacities even after repeated deep discharges.
Applications
UPS & EPS system
Telecommunication
Banks & Financial Centre
Medical Equipments
Emergency Power System
Alarm & Security system
High Power Backup Supply
Control System
Wind Energy System
