My 1 year old Fenix 16340 batteries have begun to reach the end of their service life.
I purchased seven Fenix 16340 batteries about a year ago and have been using them daily. One of them has started to drive my HDS flashlight bananas. The light works fine for about 15 minutes then is steps down from high a few levels. When I turn it off for a few minutes and then turn it on to the high level it steps up to high stays for about a minute and then steps down two levels (I have burst disabled). When I put in a new and freshly charged Efest 16340 battery everything goes back to normal and the HDS is happy. I have recycled that Fenix 16340 battery. I had hoped for at least two to three years of daily service. Guess not.
I guess the HDS light is a good indicator of battery service life given that it has 20+ step down levels.
Once all of my Fenix 16340 batteries have reached the end of their service life - which I predict will be within the month of August - I will invest in some HDS 16340's and give them a try.
