    For continuous discharge mod


    Operation Temperature and relative humidity Range

    Charge: 0~60℃ 60±25%R.H.  

    Charge at a very low temperature such as blew 0,will be get a lower capacity and reduce cycle life of the battery

        Discharge: -10~80℃ 60±25%R.H.

    Storage temperature for a long time


    Do not storage exceed half year. Must charge once when storage for half year. Must charge the battery which with protect circuit when storage for three mouths.

    13 Allow swellingThickness 10% of Initial Thickness  

    Rated Capacity at 0.2C(Min.)

    After standard charge, the capacity shall be measured on 0.2C discharge till the voltage discharge to 3.0V,


    Rated Capacity at0.5C(Min.)

    After standard charge, the capacity shall be measured on 0.5C discharge till the voltage discharge to 3.0V,

    Retention capacity



    Rated Capacity at 1C(Min.)

    Charging and discharging battery as blew conditions

    0.2C standard charge to 4.2V end-off

    0.2C standard discharge to 3.0V cut-off

    Continuous charge and discharge for 500 cycles, the capacity will be measure after the 500th cycle
