I don't care if my build is 0.5 or 0.1, I wouldn't be putting unknown, untested and overspec (most likely, since they are an "impossible" spec) on a mech mod. That truly is asking for trouble, honestly, and you did ask the question wanting actual answers right, not just something that will make you "feel" safer.
It really doesn't matter if "vendors" stock them or you "like" amazon, or whatever, it matters that you know what your batteries are and what they can and cannot do. Like you said, it's amazon so return them and buy real cells from the approved vendor list.
I am sorry to have to state the truth-- vendors who are unscrupulous/uninformed (or both) will often sell "specialty vaping cells" (or whatever) with or without knowledge that they may be dangerous. They certainly have a PROFIT margin for the uninformed vaper who is looking for "a vaping battery." So the fact that vape shops sell them means absolutely nothing.
I wouldn't even buy an "authentic" battery from a vendor, they often get rewrapped "rejects" from the big manufacturer's bins. IMRbatteries.com is a vendor that I most often use. They are rapid, professional, will arrive soon, and are of high quality. I know that I am purchasing the real thing. Often, the most trusted sellers will sell you something close to what you "think" you have gotten, specs wise, for LESS money. Plus, you know you are being safe.
By all means let Mooch test those batteries to let you know how safe/unsafe you are being, if he wants to do so. But I'm fairly certain he would tell you not to vape them in the meantime (and quite possibly not after the testing, as well).
PLEASE don't use those batteries, especially since you have no idea what they actually are. That's like a recipe for something horrid to happen, and you have been told about battery safety now. There is NO excuse to continue vaping them but if you do, just make sure it's not near other people who may have to accept the fallout of YOUR bad decision making. Not trying to be mean here, more realistic.
