10A and 2.5V cut-off after the standard charge is as follows.
Note: If charge temperature and discharge temperature is not the same,
the interval for temperature change is 3 hours.
Percentage as an index of the capacity at 25℃(=1,450mAh) is 100%.
7.7 Charge rate capabilities
Discharge capacity is measured with constant current 10A and 2.5V cut-off at 25℃
after the cell is charged with 4.2V as follows.
Note: Percentage as an index of the discharge capacity at 25℃ and 0.75A charging
(=1450mAh) is 100%.
7.8 Discharge rate capabilities
Discharge capacity is measured with the various currents in under table and 2.5V
cut-off after the standard charge.
Note: Percentage as an index of the capacity at 25℃(=1,450mAh) is 100%.
7.9 Cycle life
Each cycle is an interval between the charge (charge current 0.75A) with 100mA cut-off
and the discharge (discharge current 18A) with 2.5V cut-off.
Capacity after 250cycles,
Capacity ≥ 870mAh (60% of the standard capacity at 25℃)
7.10 Storage characteristics
Capacity after storage for 1 month at 60℃ from the standard charge,
measured with discharge current 10A with 2.5V cut-off at 25℃.
Capacity retention(after the storage) ≥ 1,015mAh (70% of the capacity at 25℃)
7.11 Status of the cell as of ex-factory
The cell should be shipped in 50% charged state. In this case, OCV is from 3.79V to
3.85V.
