    While the test results are hard data, the conclusions and recommendations I make based on these tests are only my personal opinion based on my criteria for setting a rating. Carefully research any cell you are considering using before purchasing.

    Testing cells at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved and how to minimize them.

    If the cell has only one current rating number on it, or if it only says "max" then I have to assume that the company is stating that the cell can be discharged at that current level in any way, including continuously.

    Bottom Line
    This “40A” cell is the exact same one as AWT’s “35A” 3000mAh, a rewrapped Samsung 30Q. Enough is enough, just don’t buy this cell.

    I am rating this AWT at 20A and 3000mAh. Its maximum vaping amps (MVA) limit is 25A, limited by temperature.

    The two cells that were tested were purchased for that purpose by me.

    Pulse-Current Test Results
    Pulse testing was not done due to it being a 30Q rewrap.

    Makes you want to send them the battery and tell them to make baby car seats instead.
    Thanks Mooch

    The sheer disregard for their customers almost defies belief. No other market would stand for it.

    Classic! The labels on these products are the consecuences of the foolish and philistine crowds being served by unscrupulous companies. Very much like this:

    OMFG! MOAR is better! :p

    Mooch, maybe it would be a good idea to put a special badge on review titles of misleading products. For example:
    FAKE - AWT Red 40A 3000mAh 18650…

    Of course, this means A LOT of still nice products would get ¯\_(ツ)_/¯ the badge, but hey, this is about educating the marketing label/wrap designers, don't you believe? LoL! :D

    P.S.: high capacity 16340s seldom go above 700mAh yet.

    I had considered that but then, essentially, every non-Samsung/Sony/LG/Panasonic/Sanyo battery would be tagged. :)

    I couldn't use "Fake" as they are genuine Chinese rewraps done by that particular company. They don't claim to be a Samsung, etc. I am starting to use "do not buy" in the title for the worst offenders though. A small step towards separating some of the worst out.

    You are, I noticed. The frustration is palpable.
    I had feared they had simply broken you. :D

    Actually, the unregulated "dietary supplements" sector springs to mind. :(
