12V 28AH Energy Storage Battery , AGM Valve Non Spillable Lead Acid Battery



12V 28AH Energy Storage Battery , AGM Valve Non Spillable Lead Acid Battery



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


Due to the perfectly sealed construction and the recombination of gasses within


the cells, the battery is almost maintenance free.



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.



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.

Tips and Precaution



Heat kills batteries. Avoid installation and/or operation in close proximity to heat


sources of any kind. While the operating temperature range is -15°C to 45°C,


and ideal service life will be realized when the battery is operated in an ambient


temperature of 20°C (for cyclic service applications, a range of 5°C to 35°C is





If the battery is to be installed in an air or water tight container, ventilation must


be provided. Batteries may generate ignitable gases which must not be


contained. Because of this, batteries should not be installed near spark


producing equipment.



Avoid installing the battery in an atmosphere where organic solvents or


adhesives may be present. Do not clean the battery with oils, thinners or similar


substances. Use water only. The case and cover of the battery is ABS plastic


resin which may suffer damage from these chemicals.
