not sure if I can reply here this question.. PM sent
edit : Neisius you cannot receive PM (new user) so let's say the Panas are at around same price range as the "false" 3000mah ultrafire...

I bought mine in a small electronic shop for 15 bucks (in China). Looks like a DIY product, manufacturing quality isn't great and it's not a professional grade equipment for sure, but it gives an idea of the cells capacity and that's all I wanted. Silverfox and ichoderso will do much better test when they will get the cells :thumbsup:

Good news,
just finished a first discharge test on a random PANASONIC 18650 2900mah sample. First time charge by Trustfire TR-001 at 500ma. Final voltage was 4.16A. Then wait 1 hour. Discharge by GY568+ tester at 500ma. End of test is achieved at 3.31V. For the final result, a picture worth a thousand words :
I believe after 4-5 charge/discharge break-in cycles, it should be able to reach easily 2950mah. well looks good so far 😀
doing now same test with another sample...
mAh meter / tester - More info PLZ :wave:
I'm waiting for my stock to arrive. Hopefully in coming days. When I will have it in hands, I will open the sales thread, not before. I want fast and immediate delivery 🙂

It would be interesting to get hands on some of these.
Strange that they are so hard to get, looks like NNP (LiNiCoAlO2) batteries are around for quiet some time.
There is some info about them: http://download.intel.com/idf/us/docs/PS_EBLS003.pdf
Also seems like besides EeePC high performance battery pack mentioned earlier they may be also found in some other packs.
E.g., FUJITSU FPCBP171AP and FPCBP186AP - 6 cell 10.80V 5800mAh

xpea, thank you for doing that test. If at all possible, could you please throw the switch, and test another cell at the one amp setting? Many of us run flashlights that drive the LED at or slightly over one amp; I believe many of us would be curious to see how the cell performs at that load.
Hi all, I'm waiting for the panasonic cells from xpea.
If the cells arrived me, I will test it with different currents and compare the results with other cells, I have the most UF/TF cells, this from Solarforce and AW also....let's wait and see🙂
regards from Germany,
Jens

I am hoping that *some day* a "protected" version will be available.

Jens, your equipment looks beautiful. Eagerly, I anticipate your tests at different discharge rates! *thumbs up*
the new Panasonic NCR cells arrived me yesterday!
I will test it at 1, 2, and 3A.(maybe at 5A..)
I use a new Software for better comparing the cells, but I can't import my old measurements from the other cells, and so I must take new measurements from the other cells too. I need some time for this
greetings from Germany, Jens
