12V 28ah High Rate Rechargeable Vrla Battery , Agm Separator Sealed Deep Cycle 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.
