Thanks buddy, you are responsible for most of us still having most of our fingers. But seriously as seen by the reply’s you are greatly appreciated.
after some time of common use, the wraps get signs of wear and tear that require a rewrap
After a time of regular use, the wrap show signs of wear and tear (especially at the edges) and require a rewrap
Well, it’s ideal. But lots of those so called 4 major brand battery are not even recognized by their manufacture especially top 4 manufacture already formally announced they have nothing related to E-cig industrial, also, based on my understand, under such shortage in general market, product in market always mixed with grade B/C even recycled cells together...that make this BRAND cell looks even dangerous sometime ....
If you live in France, or Italy you would have a problem to buy industrial batteries on Off-line stores
Dude, where did that comment come from? 
That's not the kind of "re-wrap" that we are talking about in this thread. 
In this thread we are talking about those mostly Chinese brand battery sellers who obtain second/third tier quality batteries from LG, Samsung, or Sony... and rewrap those cells with their own brand's wrap, often with over-rated specification on the wrap.

Well, we don't really know if these new Chinese cells are actually "new", maybe they're out of used equipment, lol.
I know, Dude

What I don't know is anybody buying re wrapped batteries. For me, it sounds like buying used socks. ...
Internal resistance would probably reveal they weren't new. I they were removed from battery packs there could be markings on the terminals indicating they were spot welded with strap connections.

Are efest rewraps? I never see them in the charts, except for 20700.
Sellers won't check and won't take them back either (most at least). Reputable places most likely won't carry them.
All this does is open up the flood gates of "auction site" battery deals. The only plus is most people don't use mechs like they used to and the ones that do generally know better. This of course means nothing to the media (when it all goes south) or people new to vaping or considering it.
Yep
Efests are rewraps that I want to SAY are fairly consistent, but sort of consistently sucky as far as ratings, but at least you (maybe nothing is ever 100% with rewraps) sort of have a sense of the rating, as it were. Some provari folks were using them when AW was not available and etc. I got sent a couple with a mod I bought and I can say (although I don't know how old they were) performance was pretty poor and I didn't wind up using them.
I will say, with some of the newer batteries, you do sometimes have to make a concession because I think they are all rewraps? None of the large manufacturers are making them yet although maybe there's one or two, IDK?
The big problem with the larger sizes (IMHO) is that often times, folks want more power from them, expect more power, and may not necessarily be DELIVERED that power, so I am super glad I am a low wattage vaper and also, some of the 1850 specs that are truly "the best" sort of rival the larger size batteries in capacity or even exceed a bad one. There has been like waves of excitement, then rewraps being retested at far less than their initial rating and etc.
So exercise caution I guess, and please KNOW I am far from expert in these matters and ANYTHING I say is up for correction, honestly.

Efest doesn't manufacture their own battery cells. Their 18650 batteries are either rejects from LG, Samsung, and Sony or they commission with a Chinese factory to supply them with new cells. The smaller (18350, 18500) and larger than 18650 battery sizes they wrap, are also commissioned by a Chinese manufacturer.

Strange. I don't buy efest, the only one I have I bought with the Nunchaku kit. Yet, against a new LG brown it lasts longer. I can't know the resistance. Both batteries were bought within 2 weeks one from the other so they have more or less the same amount of cycles. I'm not arguing, merely stating a fact.
What are the "alleged" specs of your Efest? Did you cross reference that model and specs with a review of that model of Efest by Mooch's test results?
A little hard for me to understand how an Efest could outperform an authentic LG HG2 3000mAh 20A, unless the Efest has a higher amp rating and you are vaping over 60 watts. The HG2 (at 20 amps) has a wattage limit of 65 watts.

I've only owned 2 Efest cells and those were purchased at a local vape shop back around 2011. Last time I checked they were still good, but they got low usage after the bargain bin rewrap stories truth came out. 35A? Naw, more like 10A to 12A, but they worked fine for me at 6 to 10 watts in a Provari. Once I found out that I could buy good cells for the same price I never looked back.
I'll have to stick them in the charger and see what they show for internal resistance.
