4 OUTLINE DIMENSION
Dimension: Diameter 18.4mm±0.2mm, Height 65.4mm±0.2mm. Refer to attached drawing 1.
5 APPEARANCE
There shall be no such defect as breakage of tube and deep scratch, flaw, crack, rust, leakage, which may
adversely affect performance of the cell.
6 TEST CONDITION AND DEFINITIONS
6.1 Measuring Equipment
6.1.1 Slide caliper
The slide caliper should have a scale of 0.02mm.
6.1.2 Voltage-Impedance meter
The impedance meter should be operated at AC 1kHz, and have a scale of 0.1mΩ/1mV.
6.2 Unless otherwise specified, all tests shall be performed at 25℃±2℃ and humidity of 65%RH±20%RH.
The cells used for the test mentioned should be new ones delivered a week before at most.
6.3 Definitions :
C Rate (“C”): The rate (milliamperes) at which a fully charged cell is discharged to its end voltage in one
(1) hour.
7 CHARACTERISTICS
7.1 Charge method
7.1.1 Charging shall consist of charging at a 0.2C constant current rate until the cell voltage reaches
4.2V. The cell shall then be charged at constant voltage of 4.2 volts while tapering the charge current.
Charging shall be terminated when the charging current has tapered to 0.02C.
7.1.2 Charging shall consist of charging at a 0.3C constant current rate until the cell voltage reaches
4.2V. The cell shall then be charged at constant voltage of 4.2 volts while tapering the charge current.
Charging shall be terminated when the charging current has tapered to 0.05C.
7.2 Discharge method :
7.2.1 Cells shall be discharged at a constant current of 0.2C to 2.5 volts
7.2.2 Cells shall be discharged at a constant current of 0.5C to 2.5 volts
7.2.3 Cells shall be discharged at a constant current of 1.0C to 2.5 volts
7.2.4 Cells shall be discharged at a constant current of 2.0C to 2.5 volts
7.3 Internal Impedance
The impedance shall be measured by 6.1.2.
Initial Internal Impedance ≤35mΩ.
7.4 Discharge Rate characteristics
Cells shall be charged per 7.1.1 (0.2C) at 25℃ and discharged per 7.2.1(0.2C), 7.2.2 (0.5C), 7.2.3 (1C),
7.2.4 (2C) at 25℃. The discharge capacity of each cell at respective discharge rate shall be compared
