I'm sorry you missed the relevance. I will try to "dumb it down" a bit.
Comments like "I get 4 hours" are meaningless, useless, and are of little help since vaping habits are individual an unique.
The best one can do in order to get an "apple to apple" comparison is use the resistance of the battery in conjunction with the mAH capacity of the battery for a specific model to calculate the "on time" that is available for a full charge. After that, your true "vaping time" is a function of your specific duty cycle (vaping vs. non-vaping time ratio).
The math and theory for the time calculation is pedestrian.
Batteries have a "capacity" value stated in mAH (milli-Amp Hours). Divide that by 1000 to get AH (Amp Hours)... multiply that by 60 to get "AM" (Amp Minutes).
The amps (current) drawn by a PV is defined by Ohms law. Divide the battery voltage (3.7V in these cases) by the atomizer resistance to get the PV current requirement in Amps.
Divide the Amp-Minutes by the Amps to get the Minutes.
Easy.
Why thank you so very much. That was very interesting & I'm sure you'll agree that there are lots of people on here that do not have a clue about electronics, & I'm certain that will clarify things for them.
Out of interest, have you done this with other model e-cig batteries? I'm certain the results would make a very interesting thread.
I'm a little lost here. Are you saying 501s are bad or 510s?
Typo. Sorry. 510s
One or the other or both, doesn't matter to him. And basically that's all he's saying. He's the "devil's advocate" against reality.
Which reality would that be then? I only ask as some of the folks on here seem to live in some sort of alternate one.
I don't see why I should justify myself to a mob mentality that is clearly ganging up on me, but I will. My comments are based on experience with all (not just one, but all) of the 510s that I've owned. Both from TECC & TW, & of both the Mega & both (old & new, I know there was only a mm or so difference, but the difference was noticeable) lengths of the regular. Now, either they don't perform as well as folks on here say they do, or I must be the most unlucky (former) 510 owner, as mine all seem to have come from duff batches.
Just to add, that I'm not going against the flow for the sake of it. There are obviously bad 510s out there & folks should be able to see the flip side of the coin. I only got mine because I needed a manual (work conditions make using autos that activate with noise or vibration nigh on impossible to use) I really wish I'd seen a thread on the downside of 510s before I'd bought mine (or at least that somebody had mentioned something on one of the many pro-501 threads or the newbie threads that always seem to contain at least 3 "you need a 510" posts). I would've probably waited for the manual M401s & saved myself a lot of money & bother.
Oh, & please don't presume to know what I'm saying.
