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°C 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 0.05 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 of
1,375mA and constant voltage 4.20V at 25°C, 0.02C 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 550mA with 2.50V cut-off at 25°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 2,750mA with 2.50V cut-off at 25°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 45m
7.5 Temperature Dependence of Discharge Capacity
Discharge capacity comparison at each temperature, measured with discharge
constant current 2,750mA and 2.50V cut-off with follow temperature after the Standard
charging at 25°C.
