6V 7Ah maintenance free Rechargeable Lead Acid Battery sealed for Emergency Alarm System






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

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.



Low self-discharge rate.
