A new brand of 1400 cells, it is any good?

Discharge curves looks good, the two cells tracks very fine and can easily deliver the rated 1.5A and still maintain rated capacity.

Conclusion

This cell has good capacity and can deliver some current (It is not high current).
It looks like a good cell for current up to about 2A.

Is it just the angle of the photo deceiving me, or does the positive end stick up just enough so that it will work in a torch which normally requires a button top, magnet or solder blob, such as a Klarus Mi7?

Beam me up!

The cells I have will make contact to a flat surface with the positive end.

Thanks, the 14500’s I currently have are marked 800mAh but measure 650 at best and won’t make contact so I have been looking for a replacement available from a supplier that will ship to S.A. I think this fits the bill perfectly.

Beam me up!

Thanks for the review. I have been waiting for this one.
Sounds like a very decent cell and if I remember correctly, the price is right.

I have been asked about it a couple of times, last time I was asked it had arrived and I put it directly on the test station (My queue for that test station has been rather low recently, but I expect that is fixed soon).

Thanks for testing.
Results are as i expected.
I assume their 16340 will have similar performance.

Looking for:

5” parabolic reflector (for recoil light)

Just tested my newly received PKCell ICR14500 750mAh (bought from AliExpress) @ 1A drain, using EBD-USB+ and a AA battery holder and USB-to-alligator-clip adapter (might introduce some resistance…) similar result.

791mAh discharge capacity @ 1.0A discharge rate… 3.00v cutoff.

Actually, I designated a cut-off voltage of 2.75v (have I damage the battery life by draining below 3.0v?)
(829mAh if drained to 2.75v)

The seller item specs does not indicate a standard charging current (only the max continuous charging current as stated above is 1C or 750mA). At what current is it suggested to charge this 14500 cell? Is 0.50A OK or 0.30A better?
