An 18650 is an 18650?

[Wil]

Are all 18650s the same? I think it's an indication of size... I found these, and think they'd last days in a ProVari, but I don't want to burn it out either.

NEW AW Black 18650 3.7v 2900 mAh protected lithium-ion rechargeable battery

I see it's a 3.7V, but the current is significantly better than what I have. These are 2900 mAh, compared with the 1600 mAh I have now...

Thoughts?

(note: Essentially the same question as posted in the ProVari sub-forum)

The provari uses imr high drain batteries. Those batteries can supply the amperage needed for higher voltage vaping. The standard lit ion cell won't disapate more than an amp or so while high drain is around 4 amps (at least at 14500 size not 100%the for the larger sizes) so in essence the imr at a lower mah rating should last as long as a lit ion being hit hard and drained for more amps that it can produce. Basicly if you used a regular lit ion you'd be working it harder than designed thus reducing how long it lasts, times it cab be charged, and the overall health of the battery. Bigger mah isn't always the best plan. Just my 2 copper.

That 2900mah is longer and has a flat top. The extended cap does not screw down all the way when used with the vari and you need to add a magnetic spacer to engage the top connection. I have found that the 2900 is good on my REIO grand and I stick with the recommended cell on the Vari.

It would be fine on a reo if using standard ohm attys. If you used a low resistance atty you still might be draining more amps than it can physically put out.

Just read that those are rated at 5.8 continuous and the imr is 8.6 amp continuous. You'd have to do a little math it use an ohms law caluculayor to see if what you're vaping at normally is under the rated 5.8. Im guessing it is but I also know that you will get the low power or not enough power error using those at higher voltage lower resistance. It may say they're dead sooner than they are is the only other issue id see and thenbtou wouldn't be getting improved between charge times at all.

I'm not a battery expert but I did a bunch of research when I recently bought my Provari. This is what I found that I understand.

1 -The AW IMR High Drain batteries have a Lower internal Resistance which allow the Provari, and other similar types of VVPV's, to perform at their best.

2 - The AW IMR's are Not a Protected battery because they are Ni-Mh which is considered to be "Safe Chemistry"

3 - The AW IMR's didn't cost much more than other batteries of the same size.

4 - No One, and I mean No One had anything bad to say about them.

You can put anything you want in your VVPV's but the battery geeks seemed to think that point number one was important. And for me, point numbers 3 & 4 sealed the deal.

Thanks much, all... It's been a while since I've taken a physics class.

What you're saying all makes sense... I just needed the relevant part separated out from the rest.

So, I'll stick with what I've got. Thanks again for the input!
