4.0 Outline dimensions
See the attachment (Fig. 1)
5.0. Appearance
There shall be no such defects as scratch, rust, discoloration, leakage which
may adversely affect commercial value of the cell.
6.0. Standard test conditions
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
The impedance meter with AC 1kHz should be used.
7.0. Characteristics
7.1 Standard charge
This "Standard charge" means charging the cell CCCV with charge current 0.5CmA
(1,500mA), constant voltage 4.2V and 150mA cut-off in CV mode at 23for capacity.
.
7.2 Rated charge
Rated charge means charging the cell CCCV with charge current 4A and 100mA cut-off
at 23
7.3 Standard discharge capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is
measured with discharge current of 600mA(0.2C) with 2.5V cut-off at 23within 1hour
after the standard charge.
Nominal discharge capacity 2,950mAh
Which complying to the minimum capacity of IEC61960 standard.
7.4 Rated discharge capacity
The rated discharge is the discharge capacity of the cell, which is measured
with discharge current of 10A with 2.5V cut-off at 23within 1hour after the rated
charge.
Standard rated discharge capacity 2,900mAh
7.5 Initial internal impedance
Initial internal impedance measured at AC 1kHz after standard charge
Initial internal impedance 26m
