Does not seem to be in line with HKJ´s testing, they should give a bit more.
Are these from Manafont, do they look genuine? Try to give them a cycle or two and see if they gain any capacity.
I have also 4pcs coming, I will test them and post results when they finally arrive.
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.
Looks like I have to order a new set of batteries to test.
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.
TF Flames might not be consistent, but they are a much better bet at the low end of the price range than blue or grey wrapper XXXfire batteries.
They (Trustfire) are trying hard, that is obvious.
People just shouldn't expect some special, consistent good test results, and being disappointed.
Some of the reasons are in my previous post.
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!
I hope we will share some knowledge, experience, and good products for a long time.
What is the normal price for these 3000mAh TF batteries? They are being sold here for 10,30USD but I dont know if they are fake or genuine
Did DX just start selling these? That's the first time I've seen them there. I see Manafont sells them for $11.70/2pk.

Yes they sell them, they added the batteries yesterday
Yeah, I just checked the "New Arrivals" link and also see the new TF Flames 25500's.
-Garry
I don't think potential scamming manufacturer would have any profit by making fake Trustfire batt. - They are already cheap cells.
But, who knows - Chinese can pull any trick available to make a few $.
DX overview for this TF 3000 actuallyl states that it’s capacity is 2500-2600mah. Same capacity as tested in this thread.
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.
You think they don't see HKJ web site ;)
We all should link to his web site to spread a word , and more info to naive buyers who still think that Ultrafire is good 18650 batt. manufacturer.
How do you useTaobao when is all in Chinese. Google translator?
I meant HKJ has very informative test/review website about all lithium based batteries, chargers, flashlights. Maybe the best currently.
You just type in names, no translator. Then you translate what you need, like a description for example.
Lol, we will have to learn Chinese soon.
Did you find any difference in price?
