I agree, they are not consistent with HKJ's results. It looks like I am the second person to post results which differ from HJK's findings. Inconsistent cells? Perhaps?
I will cycle them a couple of times, but to be honest I don't hold out much hope. Not when they are achieving such a low capacity from the word go. 2135mAh is ridiculous.
Edit: They were bought from Manafont and are genuine - bearing the hologram on the outer packaging etc.
There is a huge misconception about Trustfire, Ultrafire, xxxfire batteries.
First you have to ask yourself why they are so cheap,
then you go and search for any decent brand new bare 18650 cell made by: Sanyo, Panasonic, LG, Samsung, ....
then you add price of PCB, and top button add-on assembly, color print, PVC wrapping.
The truth is: Trustfire, Ultrafire will find anything 18650 size, and sell it to you.
Recycled laptop cells. Hell why not ? just print as high as possible mAh rating, and unaware people will buy because it is cheap.
I even saw the other day 5000mAh cell :)
That's why you will always get different results in your tests.
If you want good performing cell you will have to pay a little bit more, or simply play lottery hoping that your Trustfire, Ultrafire, xxxfire will perform good enough.
There's probably many fakes as you can buy printed PVCs from Taobao with Ultrafire 3000mAh and so on.
As for recycled laptop cells, that what I was asking in another thread, if the capacities they come are random, how steady (or random) they lose their capacity in time. But not just by self-discharge and 1 cycle a week. How they hold up after 50 cycles, Will they be just fine or they will be "replaceable".
Unfortunately 4 or 6 examples will not be relevant.
SpaceCowboy, I don't remember if I welcomed you to BLF or not. I'm a big fan of Cowboy Bebop. I even adopted a Welsh Corgi because that breed of dog is on CB. I hope you enjoy your stay here at BLF!
Hehe there's forum requests at DX by the clients there, why wouldn't anyone show them the link before they actually had it for sale.
Actually one of the guys there says for the 26650 that the cells are rated 500mAh but they tested them to be 4000mAh. They may have very well not tested them, as on Taobao there's the same mention.
BTW there's the mention of a 3.2A max current discharge on the 26650 TFflames.
