4. Outline Dimensions
        See the attachment (Fig. 1)
5. Appearance
        There shall be no such defects as scratch, rust, discoloration, leakage which
        may adversely affect commercial value of the cell.

6. Standard Test Conditions

    6.1 Environmental Conditions
            Unless otherwise specified, all tests stated in this specification are
            conducted at temperature 25

±5℃ and humidity 65±20%.

    6.2 Measuring Equipment
            (1) Ammeter and Voltmeter
                    The ammeter and voltmeter should have an accuracy of
                    the grade 0.5 or higher.
            (2) Slide caliper
                    The slide caliper should have 0.01 mm scale.
            (3) Impedance meter
                    The impedance meter with AC 1kHz should be used.

7. Characteristics

7.1 Standard Charge
This "Standard Charge" means charging the cell with charge current

1300mA and constant voltage 4.2V at 25

℃ for 3hours.

7.2 Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is

measured with discharge current of 520mA with 2.75V cut-off at 25

℃ within 1hour

after the standard charge.

Standard Discharge Capacity

≥ 2550mAh

7.3 Initial internal impedance

Initial internal impedance measured at AC 1kHz after rated charge.

Initial internal impedance

≤ 100mΩ

7.4 Temperature Dependence of Discharge Capacity

Capacity comparison at each temperature, measured with discharge

constant current 520mA and 2.75V cut-off after the standard charge is
as follows.

Note: If charge temperature and discharge temperature is not the same,
