12V 4AH Maintenance Free Sealed Lead Acid Battery Rechargeable for Security Emergency



Description

Designed life for floating charge is 3-5 years (20℃)


FLoat charging voltage: 13.5V – 13.8V (20℃)


Such as broadband, PVs etc through up-to-date gel technologies


Wide temperature scope of application (-15~45℃)


Best temperature of application (20±5℃)


No leaking, safe and reliable


Good deep charge cycle performance


Good over-discharging recovery performance


Standing or lying down for using, convenient to transport and install


Our gel batteries uses German origin high purity fumed silica to form sulfuric


acid thixotropic Gel and fills to the batteries with vacuum to ensure the fully


penetration of electrolyte through separators and plates pastes.

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



Environmental Services:
