Technical  Feature:

Sealed Construction


The unique construction and sealing techniques ensure no electrolyte leakage


from case or terminals.



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





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.




Cyclic Service Life


More than 600 discharge/recharge cycles can be realized from CGB CB and HR


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 years in


float service applications.



Self Discharge - Shelf Life


The self discharge rate at room temperature is approximately 3% of rated


capacity per month.



Factors that influence the Actual Capacity


The actual capacity is mainly related to the battery’s construction, manufacturing


process and operational environment. During operation, the factors that


influence the actual capacity are the discharge rate, end voltage, ambient


temperature and discharge time.






The batteries are manufactured using a range of terminals which vary in size


and type. Please refer to details as shown



Insufficient Charge


If the floating voltage is not set correctly (too low or not compensate according to


temperature), the battery system will in an insufficient charge state for a long


period of time. When the electricity is out, the battery may not be able to work


because the acid is satirized and the capacity is decreased.
