It seems that I just burn two Euros at the local Chinese shop in my town.
A friend told me they have single 16850 cells, and they do, three choices.
First two choices are the fake lightweight cells and the third is the heavier ART 5800mAh.
This is approximately 38 Gram the nylon jacket was full of printed lies, indicating electronic protection when there was none after this was removed.
Also there was text of Shelf life 10 years ... and this is a bad joke, that Supfire marketed cells using allot.
Neither Supfire this is a battery maker, but someone selling LED torches.
Internal resistance measured at 69 milliohm, the first true proof that this product is not a battery anymore.
From first fully charge 4.22V, discharge at 1.5A this deliver 1100mAh. :P
Second test charged at 4.10V & discharged at 1.1A by delivering 900mAh.
Now I am speculating that someone steal 5000mAh from this battery. :P
Unfortunately for me I did remove the nylon jacket and now I lost the chance to request product warranty.
This is the fate of a Blogger, his wallet gets burned so all of you to be safe.
