(1,500mA), constant voltage 4.2V and 150mA cut-off in CV mode at 23℃ for 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 23℃ within 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 23℃ within 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 ≤ 26mΩ

8.0. Mechanical Characteristics
8.1 Drop test
Test method: Each fully charged cell or battery is dropped three times from a height of
1.0 m onto a concrete floor. The cells or batteries are dropped so as to
obtain impacts in random orientations. After the test, the sample shall be
put on rest for a minimum of one hour and then a visual inspection shall be
performed.
Criteria: No fire, no explosion.
Drop test shall be performed with the IEC62133 standard
8.2 Vibration test
Test method: As to the UN transportation regulation(UN38.3), for each axis (X and Y
axis with cylindrical cells) 7Hz→200Hz→7Hz for 15min, repetition 12 times totally
3hours, the acceleration 1g during 7 to 18Hz and 8g (amplitude 1.6mm) up to 200Hz.
Criteria: No leakage, with less than 10% of OCV drop
Vibration test shall be performed with the UN38.3 standard
