the interval for temperature change is 3 hours.
Percentage as an index of the capacity at 25 (=2550mAh) is 100%.
7.5 Temperature Dependence of Charge Capacity
Capacity comparison at each temperature, measured with discharge constant current
520mA and 2.75V 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.
P
ercentage as an index of the capacity at 25 (=2550mAh) is 100%.
7.6 Charge Rate Capabilities
Discharge capacity is measured with constant current 520mA and 2.75V cut-off
after the cell is charged with 4.2V as follows.
Note: Percentage as an index of the capacity at 25
(=2550mAh) is 100%.
7.7 Discharge Rate Capabilities
Discharge capacity is measured with the various currents in under table and 2.75V
cut-off after the standard charge.
Note: Percentage as an index of the capacity at 25 (=2550mAh) is 100%.
