    • 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.


    ● 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.

    Storage Temperature (℃)≤2526~3334~40
    Storage Time (Month)631

    ● Batteries should be recharged within the storage life or before using.

    Charging methods: maximum charging current 1.65A, constant voltage 2.45±0.05V/cell (25℃);

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


    Using ModeCharging VoltageTemperature CompensationMax Charging Current
    Standby Use2.275±0.025V/cell (25℃)-3.3mV/℃/cell1.65A
    Cyclic Use2.45±0.05V/cell (25℃)-5mV/℃/cell


    • Do not use at the places near fire. Hydrogen gas generated from battery may cause fire and explosion.

    • This 12v battery is only for starting engine. Do not apply for other uses.

    • Keep out of the reach of children or the personnel who do not understand the manual. It may cause blindness or severe burn.

    • When using the battery, wear safety glasses and rubber gloves.Sulfuric acid may cause blindness or severe burn.
