In this case i bought retail packaged fairly genuine looking item.
However peeling off label reveals beaten up, scratched and dented body. Print is black ink, not etching/pressing.
Writing as follows:
Reverse side is blank with some more scratches and dents.
Weight of the battery is 1-2g less than original (33g vs 31-32).
Googlefu reveals some chinese manufacturer (TIANJIN LISHEN BATTERY JOINT-STOCK CO LTD) and "Li-ion Prismatic" type (whatever that means).
Never i seen it described as samsung product.
Will add photos later.
I am pretty sure its fake, can someone comment on my findings ?
