Test/review of LG 18650 F1L 3350mAh (Purple)

[HKJ]

LG 18650 F1L 3350mAh (Purple)







Official specifications:

• Nominal capacity: 3350mAh
  
  Minimum capacity: 3250mAh
  
  Nominal voltage: 3.63V
  
  Maximum charge voltage: 4.20V +/- 0.05V
  
  Maximum charge current: 0.5C (1625mA)
  
  Standard discharge current: 0.2C (650mA)
  
  Maximum discharge current: –20°C ~ 5°C: 1625mA, 4°C ~ 50°C: 4875mA
  
  Operating temperature: Charge: 0°C _{45°C, Discharge: –20°C} 50°C

This is high capacity cell from a older generation.











The two cells tracks fairly well, but cannot do more than 7A (That us fine for a 5A rated cell).



















Conclusion

This was a good high capacity cell some years ago, but it lacks the current ability of modern chemistry.



Notes and links

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
