    These tests below only note the ESTIMATED ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.

    Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition.

    Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.

    If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.

    Bottom Line
    This is ridiculous. This cell’s true rating appears to be under 10A but AWT has rated it at 40A on the wrap. I recommend not buying it or using it at any level. At just 20A, one half of the 40A rating given to this cell by AWT, it reached a temperature of 113°C!

    PLEASE REMEMBER: There are no 18650’s we can buy with a capacity over 3000mAh that can have a rating over 10A and many are rated down near 3A.

    Several cells were purchased directly from AWT and donated for the purposes of testing by someone who prefers to remain anonymous. Thank you!

    Performance Specs
    - DC Internal Resistance = 30.8mOhms (milliohms) average for four cells.
    - Total energy delivered down to 3.2V at 5A continuous = Not measured
    - Total energy delivered down to 3.2V at 10A continuous = Not measured

    Wow. And there was a time AWT was the standard for a button top for Provari users. Thank you Mooch for the heads up on this one. I erroneously thought AWT would be one of the more trusted rewrappers. Now I know better.

    I could be wrong, but I thought the AW button tops are not the same company as AWT.
    Since AW had a flood a couple years ago, the factory closed and the button tops are no longer available.

    Well, there you go. My bad. I stand corrected. Goes to show how these names can get confusing. Yet another reason rewraps can be an issue.

    AW and AWT are two different companies and should not be confused.


    AW has been one of the better trusted brands on the market. At the time the Provari was being developed, Provape's engineers tested all the available high drain batteries on the market, and chose AW batteries as the best to design the Provari around. Provape went so far to even recommend only AW high drain, button top batteries for use in the Provari.

    The requirement for a button top battery was Provape's answer to prevent reverse battery errors. The button top fit nicely into the circuit board and allowed the battery to make electrical contact; put in the wrong way the flat negative end of the battery could not make electrical contact. This was called "reverse battery protection".

    AWT seems to have always had a reputation as a poorly performing re-wrap company. There was some hope when the company bought out a respected battery manufacturer a few years ago by the name of MNKE, but AWT continues to put out poorly performing batteries.


    EDIT: Excuse my brain fart. I confused AWT with IMREN. Sorry for my mistake.

    Let me say it in that way....the UL-File with the Number MH46698 on the orange IMR-18650 does not even exist. A fraud? and as far as I know MNKE has never been a battery manufacturer, but also a rebranding company...

    I can't really confirm this one way or another. All that I know is MNKE had a very good reputation as a quality battery a few years ago... one of the first 18650 30 amp continuous, 1500 mAh batteries available at the time... until IMREN bought them out.

    "IMREN (formerly MNKE)- Top 10% are available to consumers, their top 5% are reserved for car companies only. Since IMREN bought out MNKE can no longer call them a top cell manufacturer. Not because they are no longer making good batteries, but because the bare cells sold to the public are grossly over inflated when it comes to their amp ratings."
