6.1 Environmental Conditions
Unless otherwise specified, all tests stated in this specification are
conducted at temperature 23±3°and humidity under 65%.
6.2 Measuring Equipment
(1) Amp-meter and Volt-meter
The amp-meter and volt-meter should have an accuracy of the grade 0.5mA and
mV or higher.
(2) Slide caliper
The slide caliper should have 0.01 mm scale.
(3) Impedance meter

7. Characteristics
7.1 Standard Charge
This "Standard Charge" means charging the cell with charge current of
0.5C(1,375mA) and constant voltage 4.2V at 23°C, 0.02C(55mA) cutoff.
7.2 Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is
measured with discharge current of 0.02C(550mA) with 2.50V cut-off at 23°C
within 1 hour after the Standard charge.
Standard Discharge Capacity ≥ 2,750mAh
7.3 Rated Discharge Capacity
The rated discharge capacity is the initial discharge capacity of the cell, which is
measured with discharge current of 1C(2,750mA) with 2.50V cut-off at 23°C
within 1 hour after the Standard charge.
Rated Discharge Capacity ≥ 2,668mAh (97% of 2,750mAh)
7.4 Initial internal impedance
Initial internal impedance measured at AC 1kHz after Standard charge.
Initial internal impedance ≤ 35mΩ
