Fenix top-of-the-line 18650 battery.
January 1, 2019
This is Fenix's best battery without a doubt. I used these in the past, where it holds a charge for a long time with no charge degradation when not used.

Great while it lasted

Worked great for 6 months then the top twisted off. I assume it was from tightening and loosening the flashlight to put it in and take it out.

ProsSeems like a good value for a well protected 18650.

Still on first charge.

Received battery and put it on charge. It took a long time to charge (slow charge rate) as it must have been pushing lots of mA into it. Have been using it in my Fenix light and have no indication it even needs recharging (light is supposed to tell me when battery is low). Doing better than alkaline in my former EDC.
ProsMade for my flashlight, fit, capacity

High Capacity Li-Ion Battery With Multiple Protection Features
June 6, 2016
Excellent charge capacity for high-drain applications. Seems very solid & well-designed, with numerous built-in protective features (overcharge protection; over-discharge protection; and short circuit protection), thus precluding nearly all possibilities for accidental fire or explosion during recharge and use. Performs superbly in my Fenix E35.
ProsSolid, well-designed. Multiple built-in protection safeguards. 12-month free warranty. High impact resistance.
ConsA bit expensive, but justifiable in light of the many features. Longer charge time at 0.5A owing to high capacity, but can be shortened by charging at 2A.

My First High Quaility Flashlight / Batteries
April 15, 2016
I just bought the Fenix TK75 Flashlight and of course needed batteries and these were suggested by the site, so I ordered a few, 8 actually as I also bought 1 battery extender for the light for added run time. So far the batteries seem to have to power the TK75 needs as I cant believe how powerful this light is. I certainly winced at the $20+ cost for each one, but they are supposed to be able to be recharged up to 500 times with a 75% recharge return rate. I will update this after I have had the batteries for awhile to see if the charge rate holds up and the overall reliability and build of the battery.
ProsHolds a strong charge and great build for longer run times and reliability. Looks extremely well built. Has a lot of built in protection technology to protect the battery and any device it is being used in. My Fenix TK75 runs great with them. (What an awesome Flashlight, My 1st high quality light). I am going to buy 1 more Battery extender for even more run time for my Fenix TK75. I have read it will hold up to 3 extenders, but recommends using no more then 2 for a total of 3 battery stations on the light with each holding 4 batteries.
ConsCost!! At $21.00 each, they are certainly not the cheapest battery on the market and this light needs a minimum of 4 of them to run properly, but not very long on the Turbo setting 140 minutes, the mid strength will go for almost 12 hours On the low setting it will go 270 hours!! Add a battery extender & 4 more batteries and double all those run times!!! The cost should be offset by being able to almost totally recharge (75% recharge rate) battery a reported 500 times. I will see if this claim holds true. I will update this when I have had more time to research the capabilities and build of the battery.

Fenix 18650 Li-Ion cell, 3.500 mah
February 27, 2016
I needed a battery for my Fenix pd35 flashlight to replace the cr123 a cells since the 123 cells didn't last long at all. I also wanted a protected cell since these cells can be very dangerous. I don't know who makes the cells for Fenix but I assumed that Fenix would not sell an inferior product. The cell is poweful and to date has performed well. I use it nightly when walking the dog and it has not reached the low voltage warning yet. I am pleased with my purchase from Battery Junction, I feel that the price was right for this cell and shipping was within the time stated by Battery Junction.
ProsPowerful, long lasting
ConsTakes a long time to charge at a 500 mah charge rate
