LG 18650 C4 2800mAh (Brown)







Official specifications:

  • Nominal capacity: 2850mAH

  • Minimum capacity: 2750mAh

  • Nominal voltage: 3.65V

  • Discharge end voltage: 2.75V

  • Standard charge: 1375mA (0.2C)

  • Max. charge voltage: 4.2V +/- 0.05V

  • Max. charge current: 2750mA (1C)

  • Cycle life: 300 cycles to 75% charge/discharge 0.5C

  • Max. discharge current: 1375mA –20°C ~ 5°C, 5500mA (2C) 5°C ~ 45°C, 4125mA 45°C ~ 60°C

  • Operating temperature: charge: –3°C ~ 50°C, discharge: –20°C ~ 60°C



This is a medium capacity cell with standard current capabilities.










Very nice discharge curves, capacity is constant up to a bit above rated current.





















Conclusion

This is a good quality cell for lower current usage (i.e. a couple of amps).
