Yeah i think my main charge leads, soldering and the rare earth magnets might make a slight diffrence, but still good for reference as 0.1 volt is not much.
Im not confindent DX will maintain sending out good cells and it might end up like the trustfire flame 18650,s they where selling.
The cell i tested i belive is a 100% geniune cell, i have pulled apart the cell to confirm, to see pictures of the cell i tested and striped look here (Manafont cell not DX)
Looks what a strange shape the plus pole has now compared to older pics in the thread, sure something is different in this new batch! Better or worse cannot say without testing, but sure they aren't the same they were before.
Just took delivery of two trustfires from ebay seller £10.88.and two from amazon £13+.
when my bt-c3100 charger arrived i decided to capacity test them just to make sure they are all around 4400mah.
To my amazement they are all 5000mah+….5166,5149,5208,and a shocking 5360mah.
not sure which battery came from where ,but if my charger is working correctly this would indicate trustfire have upped the ante on battery capacity/value.! not sure how to add photo,s but rest assured i took some .and will happily email attach.IMGP0737!
Greetings Darkness,
I thought I was losing it here.
Just picked up a pair of TF 26650’s from E-Bay for $15 delivered.
Charged and tested drain 2x with my iMax B6.
I ran 2 charge up and down cycles then did final tests on both.
Capacity was 5427 & 5398mAh for the 2 batteries at 1 amp draw down to 3.0v.
I thought my B6 was off….
I do have pics of the charge results I can try to get up, or I can E-Mail.
Cheers
added item 2-3-15: I noticed that my tested was stopping at 330 minutes. Found a cutoff timer was stopping test before complete. Changed timer to 360 minutes and capacities went up.
Added I-Max B6 discharge test pics with 360 minute timer:
I was really expecting something in the range of 4000mAh for these, but ran them 2x each through my B6 to test.
Here is the purchase from E-Bay:

Batteries test OVER 5000mAh……wow
LOL the last line is what I posted in my purchase note on the item, not from the seller.
This thread and it's info is over 2 years old. A lot has happened since then, but basically, anything with fire in the name is still not likely to be the best to buy, nor will in necessarily be trustworthy. There are plenty of good cells sold by dealers like Mtn Electronics, (RMM), and Illumination supply, but you won't see Trustfire on their web sites. They are just not good batteries to have faith in, since they are inconsistent and copied so much. Some are even used cells, that had new labels put on. Happens all the time. I try to stick with cells from well known and respected sellers.
Most of the time the “Fire” suffix means ‘danger’, indeed.
However, I personally have not had any of apx 18 total, Trustfire batteries be any less than I expected. Most of them are 14500’s, with 2 - 18650’s and now 2 - 26650’s. They have all done very well, at a reasonable cost.
Buying from seller with good history is a good place to start any purchase.
Cheers,
As above, I just ran at 1.0A discharge, nothing else.
I have/had 2 lights that took the 26650’s. Gave one away at Christmas and still have the one with a head that pivots to a 90-degree angle….
Personally I see little or no difference in brightness between the 18650 Sanyo battery and this 26650.
I would expect it to run much longer with the 26650.
