I'm glad there are reputable independent labs who are checking the specs of batteries like
Dampfakkus so that we are even aware of the specification discrepancies in the first place. This helps consumers to make wiser choices in the batteries that we use in our mods. We can be on the alert that some batteries are not what they are advertised to be, and could be dangerous if we believe what the manufacturer or reseller quotes. Apparently there is no regulatory agency insuring that battery manufacturers are staying on spec for their product.
The Japanese/Chinese battery industry has become extremely competitive and some manufacturers & resellers will go to any means possible to gain a competitive edge in the market. Corporate greed at any cost to reputation or safety. Some have earned a reputation of being reputable (AW, LG, Panasonic, Samsung) while others have been found to be disreputable (Efest, EH, Surefire, Trustfire, Ultrafire).
The worst offenders make counterfeit batteries. They take the rejects of the respectable manufacturers and re-wrap them. Others harvest the used batteries from old laptop computers and re-wrap them. These become inferior clones of popular brands like AW and Sony. It's a very profitable business -- buy a battery for 10 cents, rewrap it, and sell it for $10. All the AW batteries sold on Alibaba, a major supplier resource in China, are counterfeits; many of those are purchased by resellers and end up on Amazon & Ebay.
Even a reputable vendor like Illumination Supply was recently duped when they unknowingly got a shipment of fake Sony's. On initial inspection they appeared to be genuine, but something was amiss. Further investigation found them to be re-wrapped Samsung INR18650-25R 2500mAh 20A. Not a bad battery to be sure, but only 20 amps continuous and not 30 like they were supposed to be. Illumination did the right thing and offered a full refund to customers who purchased these batteries.
And then there is the confusion of continuous discharge rate vs pulse discharge rate. One is an industry standard which is useful to compare one battery against another spec wise; the other is rather meaningless. I'm amazed at the number of cloud chasers who are running 0.1 ohm resistance on their batteries which is clearly above spec for any battery currently available. How many are running the "35" amp purple Efests and using that resistance and believing they are really 35 amps? They have no margin for error.
Becoming more and more commonplace is the phenomenon of first time vapers who are leaving B&M shops with unsafe mechanical setups with inadequate batteries and absolutely no instruction/education on safety.
http://www.e-cigarette-forum.com/forum/new-members-forum/596177-new-member-need-help-stingray.html Vaping has been growing by leaps and bounds, but I'm not certain that I like the direction things are going. We were supposed to take up this venture to be a risk reduction against tobacco product use, but it has become replaced by a competitive extreme sports activity. This was culminated last weekend when a spectator's mod exploded during a cloud chasing contest at Vape Blast.
