Klarus 16340 K-03 650mAh (Yellow)







Official specifications:

  • Rated voltage: 3.7V

  • Rated capacity: 650mAh

  • Charge voltage: 4.2V

  • Discharge cut-off voltage: 2.75V

  • Cycle life: 300 cycles

  • Protection discharge current: 7uA (Max)




This is a RCR123/16340 cell from Klarus (It is not listed on their website, but can be seen in one of their chargers).











The discharge curves looks fairly good, especially for 16340 cells.















Conclusion

For protected high capacity RCR123/16340 cells they look good, but like many other protected 16340 cells they are a bit long.

I hate it when I have a typo in the header, to fix it complete I need to change around 100 places. I am not going to do that, I will only change the actual title, not the filenames.

Thank you for these helpful reviews. The battery length information given here is particularly useful for me. And on the comparison page (linked above.)
