That battery is a huge hoax and has been posted long ago.
For the first... The batterys looks original but i can doubt that they are really. The chinese batterys are good. Some even better then japanese or european batterys, but there is low end.
I think these are aftermarket non-genuine but could be good batterys, maybe worth the price maybe not... it's your choice.
