1
Standard
Charge
標準充電
Charging the cell initially with constant
current at 0.2C and then with constant
voltage at 4.2V till charge current
declines to 50mA.
先用 0.2C 恒流充電至 4.2V ,再恒壓 4.2V
電直至充電電流 50mA
N.A.

Initial
Capacity
初始容量
The capacity means the discharge capacity
of the cell, which is measured with
discharge current of 0.2C with2.5V cut-off
voltage after the standard charge.
該容量是指標準充電後0.2C 放電至 2.5V 截止
電壓所放出的容量。
3350mAh

測試條件:
充電:0.2C 充電到 4.2V
放電:0.2C 放電到 2.5V
當放電容量降至初始容量的 75%所完成的
环次數定義為該電芯的循环壽命

Self-discharge
自放電
After the standard charging, storied the
cells under the condition as No.4.3.4 for
30days, then measured the capacity with
0.2C till 3.0V
標準充電後, No.4.3.4 條件下貯存 30 天,
再以 0.2C 放電至 2.5V 所放出的容量。
