7.1 Standard charge
马原读书笔记This "Standard charge" means charging the cell CCCV with charge current 0.5CmA
(1,000mA), constant voltage 4.2V and 100mA cut-off in CV mode at 25℃for capacity.
.
7.2 Rapid charge
Rapid charge means charging the cell CCCV with charge current 4A and 100mA cut-off at 25℃
7.3 Nominal discharge capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is
measured with discharge current of 400mA(0.2C) with 2.5V cut-off at 25℃within 1hour after the standard charge.
Nominal discharge capacity ≥2,000mAh
Which complying to the minimum capacity of IEC61960 standard.
