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

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.

STORAGE

Batteries should be stored in dry and clean warehouse which has good air exchange system. Batteries should avoid direct sunlight. Batteries should not be near to heat (such as radiator, the distance should more than 1m). Batteries should avoid any toxic gas and organic solvent.

When the ambient temperature is less than 25, the longest storage life is 6 months. If ambient temperature is higher, the longest storage life varies as specified in below chart.

Batteries should be recharged within the storage life or before using.Charging methods: maximum charging current 1.2A, constant voltage 2.45±0.05V/cell (25);

Charging time: 15~20h; Temperature compensation coefficient: -5mV//cell.

Warning

• Replacement of battery shall be performed as per following order. If failed, it may cause fire and explosion. Remove cable from negative terminal first.Connect cable to negative terminal last.

• When connect cable to battery, make sure not to get changed post of +and -. It may cause the damage of electronic components or fire.

• When ueing the battery ,handle with care,sulfuric acid may cause blindness or severe burn.
