Discharge rate capabilities
Discharge capacity according the discharging current is measured with 3.0V
cut-off after the standard charge is as follows,
| Discharge Condition | ||||
| Current | 0.2C (640mA) | 0.5C (1,600mA) | 1C (3,200mA) | 2C (6,400mA) |
| Relative capacity | 100% | 95% | 90% | 80% |
Note: Typical capacity(3,270mAh) is 100% as an index of the relative capacity.
