Project Description
| No. | Item | Spec | Note |
| 1 | Model Number | 4280113 1S2P / 8000mAh | |
| 2 | Charge Limited Voltage | 4.2V | |
| 3 | Nominal Voltage | 3.7V | Cell shipping Voltage between 3.6V ~3.9V before |
| 4 | Nominal Capacity | 9600mAh@ 0.2C Discharge | Nominal Capacity refer to the capacity of 0.2C discharge with 2.75V cut-off voltage, after charging with standard method. |
| 5 | Cycle Life | 300 Times | One cycle refer to one charge period and then one discharge period. Test condition: Charge: 0.2C to 4.2V Discharge: 0.2C to 2.75V The cycle life is the cycle times when the discharge capacity is about 80% of the rated capacity. |
| 6 | Self-discharge | Residual Capacity>90% | After standard charging, storied at 25°C±0.5°C for 30 days, then measure the capacity as item 4. |
| 7 | Impedance | Typical: 41mΩ | After standard charging, measure the internal resistance with AC1KHz |
| 8 | Max. Charge Current | 1C | |
| 9 | Max. Discharge Current | 1C | |
| 10 | Discharge Cut-off Voltage | 2.75V | |
| 11 | Operating Temperature | Discharge:-10°C ~ +55°C Charge: 0 °C ~ +43°C | Cells must be storied at 3.6V-3.9V. During long period storage, cells should be maintained every 90 days. The method is to do a charge-discharge cycle with standard method, then charge to 3.7—3.9V. |
| 12 | Storage Temperature | -20 °C ~+45°C | |
| 13 | Cell Weight | Approx: 160g | |
| 14 | Cell Dimension | Length： 115mm Max Width： 81.0mm Max Thickness： 9.0mm Max | Measured with weighting 300gf at 25°C±0.5°C Not including Tabs |
| 15 | Connector type | JST SYP-02T-1 + socket | 2.54mm*2pins |
