Test/Review of Efest 16340 850mAh (Black) 2014

Efest 16340 850mAh (Black) 2014



Official specifications:

  • Min Capacity: 850 mAh
  • Typical Capacity: 850 mAh
  • Nominal Voltage: 3.70V
  • Size: Max.16.63x33.98mm
  • Weight: 25g




The capacity is specified way to high as it usual is with 16340 batteries.










The battery has a very stable capacity, independently of load. This is much better than last time I tested this battery.















Conclusion

The battery does not have the highest capacity of 16340 batteries, but it does a good job in the 1A to 2A range, making it a good fit for many flashlights.
I will rate the battery as acceptable.

Thank you for the review, HKJ! It appears the cell is dented. Was there any damage to the box?

The cell is not dented, but the label has a bump where it crosses the protection strip.

Thanks HKJ. Looks like Ill stick to my 550mAh red V2 since its better at high current. :)

No surprise there, IMR is supposed to be better at high current.

Yupp... :)
