Nitecore 16340 NL166 650mAh (Black-yellow)



Official specifications:

  • Battery Capacity (Mfg Rated): 650 mAh
  • Battery Form Factor: 16340
  • Battery Rated Voltage: 3.7 V
  • Charge cycles: >500
  • Max. output current: 4A
  • Charge current: Max. 650mA, recommended 300mA
  • Weight: 17.8g
  • Size: Diameter: 16.6mm, Length: 34.8mm




This cell is Nitecores substitute for a CR123 cell, but voltage is higher and capacity less (This is not Nitecores fault).












The cells do not track very well at higher current.















Conclusion

I do not like it when cell are different, this means it is best not to use them in series.
But looking at the available selection of 16340 batteries this cell is not bad and fairly short for a protected cell.



Notes and links

This cell will not always replace a CR123 cell, see here for more info

Thanks for the review!

I have had this cell for more than a year, it works fine and I appreciate the protection. But now I mainly use IMR cells for the higher current capability.
