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


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.

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


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


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.
