Why do my AWs and AWTs feel so different

    Okay my AWs are 1.5 years old. My AWTs are 2.5 years old.

    They are both 350s and the AWs are 12a and the AWTs are 10.5a.
    Not an issue as I build for 4 Amps, tops.
    They are both at 4.18 but the AW hits noticeably harder.


    I thought that the cdr has no difference aside from builds and suitability? I thought that the only difference the age would make would be longevity of a charge?
    It seems my battery knowledge isn’t as sound as I thought.

    Can somebody help me out?

    Although both are re-wraps the AW's are a substantially better battery

    How hard a battery hits is a function of its internal resistance.

    Your AWs are newer and had a higher CDR to begin with, which is likely indicative of a lower internal resistance when new.

    Internal resistance definitely increases with age and cycles. Check out the difference between the two pairs of LG HG2s in the data I posted here. Both pairs are the same age, but one pair has been in storage while the other pair has been used. I don't yet have a good handle on what age alone does. That will take some time. :)

    This I know.
    However, I thought that would only account for the cdr which is 12a as opposed to 10.5 (I think), longevity, higher calibre of initial battery rewrapped & the mah which is 8 as opposed to 700.

    Just saw your name. No luck in finding the screw for heron/spheroid I’m afraid

    After trying a number of highly rated 18650s I like Samsung 30Q, LG HG2's, and Sony VTC6 best for vaping MTL at 3 to 4 amps. CDR on those yield long vape times at low wattage. All three rate highly on Mooch's discharge tests.

    Cheers mate. The majority of my batteries are 25rs & vtc6s but I do like to use my 490s and 350 mechs so that’s what the 350s are for.

    Fixed that for you. ;)

    As a battery ages the mAh of the battery degrades, as the mAh degrades so does the batteries c rating (amp limit). So down the road, for example, a 20A battery may only be a 10A battery.

    Because the 18350 and 18500 batteries have a smaller capacity and amp rating to begin with, they tend to show their age (decline in performance) faster than the larger batteries. You pay a price in performance and longivity because of their smaller size.

    Although Mooch hasn't tested them, the AW 18490 battery is actually an incredible performer with an 18 amp CDR and 1200 mah, far better than any other battery in its class.

    As AzPlumber and Rossum stated above, the AW brand is substantially a better battery than AWT. A simple look at Mooch's tests for AWT reveal the AWT's underperform below their advertised specs, in particular their 18650's. Although I don't use 18350 or 18490/18500 batteries any longer, but when I did I used only AW batteries for my Provari's.

    AW Red (button top) 15C/12A 800mAh [​IMG]
    • Top 3 performer.
    • Good cell-to-cell consistency.
    • Damage started at 25A pulsed.
    AWT Yellow 10.5A 800mAh [​IMG]
    • Top 3 performer.
    • One cell had higher voltage but a bit less capacity.
    • Can be pulsed to 20A.
    The AWT 18650 batteries have a poor track record:
