Since it’s a bit difficult to ship bare batteries to my country, I chanced upon a local seller here that has this Vapcell G50 at a reasonable price, so I got a few.
I just got the batteries a few moments ago. But I’m wondering if these are genuine or not.
I took some pictures and measurements. I am now loading the battery to my MC3000 to test capacity.
The characteristics (dimensions, weight) seem to match the findings above…
how it looks: (seems to look quite similar, although maybe someone can point out if there are notable differences from a genuine 50G)

diameter: (~21.1mm)

weight: (~69.7g)

AC IR measurement (YR1030 tester), from shipped condition: 13.3mOhms @ 3.58v

even has a Samsung type of date code visible underneath the wrapper:

Also, the “scratch me” authenticity sticker reads “Scrstch me” — but on closer checking, the picture HKJ posted above also reads “Scrstch me” — so it’s the same typo on the genuine Vapcell G50 sticker.
BUT there is 1 glaring issue:
it does NOT have a recessed top like what a genuine Samsung 50G / Vapcell G50 is supposed to be:

So, is this possibly a fake Vapcell G50?
(I’ll probably be able to have a more convincing answer after I do a capacity test)
