Samsung battery authenticity

[RipCigs]

Taking the advice of ECF members, I'm planning on buying Samsung INR18650 25R batteries for a 30w device (as opposed to my current Panasonic that has a 6ish max amp output). My local vendor has them, but two things are strange to me.
1.) Their price is actually a little cheaper than Fasttechs, usually products there are quite more expensive
2.) They are green, while FT and a couple other places i've googled has them as blue

This is the vendor site:
Baterija Samsung INR18650 25R 2500mAh - 18650 - Li-on, Ni-Mh baterije - Baterije i punjači E cigarete | E tekućine
This is how they look pretty much everywhere else:
$9.75 Authentic Samsung INR18650-25R 3.6V 2500mAh Rechargeable Li-Ion Batteries (2-Pack) - 35A peak discharge / 22A continuous discharge at FastTech - Worldwide Free Shipping

So are the batteries from the first site fake or what's the deal with that?

Apart from the Sony green, all the colour batteries on that site seem to be off. But I am absolutely no expert on batteries and have a four inch livid bruise on my thigh to prove it. Probably the man to ask would be someone like @Baditude .

Hi Rip. I'm not a battery guru like @Baditude, but I do know from reading the forum that there are many rewrapped batteries around. My first impression was "if it's too good to be true then it usually is".

Baditude has a blog that explains most of the batteries :Baditudes Blogs Baditude's blog | E-Cigarette Forum You'll find a list of acceptable batteries in his blogs.

Samsung switched to green a while back but mostly you still see blue as there are so many still in stock. Eventually all Samsung 25r's will be green. Afaik, no one has documented a counterfeit 25r yet, which is only one of the reasons this is the battery to get. All the fakes are Sonys, buy those green Samsungs with confidence.

Thank you!
I just found a discussion on FT forums about the same topic, the conclusion was pretty much what you just said. Cheers!

I have some blue ones direct from FT and sold as Authentic, and some green ones from Amazon, think the latter may be fakes as the printing on them smudges when rubbed, although both appear to last about the same time and act the same in a regulated mod.
