He claim that they're "100% Original BST-41 New Sony Ericsson Battery X1 X-1 " and "From Sony Ericsson Singapore (NOT CHINA FAKE BATTERY)"
with the price of 17.99$ and free shipping so, I think I should give it a try.
As suspected, it is a fake, very neat fake I must say.
As you can see, they are almost identical.
Hologram reflects at ~30 degree. The fake hologram will elevated from label a little (like stick them on top), but the original will smooth across surface.
Hologram closeup. The fake one have more pixelation than the original.
Look at both SE logo and the word "SONY ERICSSON" around it.
Label closeup. Look at "Sony Ericsson" and "+" (positive), they will have some blur edge and not crisp.
Label closeup (lower part). The word "WNBTS" alignment off a little.
Back side. The fake one will have overlapping label.
Top side. You will notice that the battery shape is not identical, the fake one will have round edge, the original will have more square like edge. This is the easiest way to detect.
Another consideration is the "Moisture Sensor", the fake one will have "plain paper" instead of the moisture sensor (I have tried pouring water over it and the color won't change) and the size is larger too.
Bottom side. The original will have a hole (to depress pressure in case of exploding).
As of now, I've contacted the seller and ask him whether this is the original or not.
He replies "Yes it is original sony battery.. pls try to use it and by using it, u will know it is original."
What should I do?
File a dispute to Paypal? Contact SE to confirm it? Report the item to ebay?
I want to hear an opinion from you guys.
Thanks everyone who read this.
