Criteria
|
1 | Rated Capacity at 0.2C(Min)
|
After standard charge, the capacity shall be measured at 0.2C discharge till the voltage discharge to 2.0V.
| ≥5900mAh
|
2 | Cycle Life
|
Charging and discharging battery as below conditions: 0.2C standard charge to 3.65V end-off 0.2C standard discharge to 2.0 V cut-off Continuous charge and discharge for 2000 cycles,the capacity will be measured after the 2000th cycle
| ≥ 80% of initial capacity
|
3 | Capacity retention
|
After fully charged the battery in accordance with standard charge condition at 20~25℃, then storaged at an ambient temperature 20~25℃ for 28 days. Measure the capacity after 28 days with 0.2C at 20~25℃ as retention capacity
