Cell Electrical characteristics for Power Bank 3-5C 18650 Lithium Ion Cylindrical Batteries 3.7v 2200mAh
1 Rated Capacity at 0.5C(Min.)0.5C
After standard charge, the capacity shall be measured on 0.5C discharge till the voltage discharge to3.0V,
the capacity can not less than 2150mah
2 Circle life
Charging and discharging battery as blew conditions
0.5C standard charge to 4.2V end-off
0.5Cstandard discharge to 3.0V cut-off
Continuous charge and discharge for 300 cycles ,the capacity will be measure after the300th cycle
3 Capacity retention
The battery to be charge in accordance with standard charge condition at 20~25℃,then storage the battery at an ambient temperature 20~25℃ for 28 days.
Measure the capacity after 30 days with 0.2C at 20~25℃ as retention capacity
the capacity can not less than 80%
4 Temperature Dependence of discharge capacity
Cells shall be charged per 3.6 and discharged @0.2 C5A to 3.0 volts. Except to be discharged at temperatures per Table 3. Cells shall be stored for 3 hours at the test temperature prior to discharging and then shall be discharged at the test temperature. The capacity of a cell at each temperature shall be compared to the capacity achieved at 23 ºC and the percentage shall be calculated. .
Discharge Temperature | -20℃ | -10℃ | 0℃ | 23℃ | 60℃ |
Discharge Capacity (0.2 C5A) | 40% | 50% | 80% | 100% | 95% |
