That seems bizarre even in the world of battery scams. You think a Chinese company is putting "Made in Japan" on the battery, or is a Japanese company putting Chinese characters on it? Obviously it can fool Westerners, but it seems like a really, really dumb mistake.
So how does it work for you?
I bought probably the same "Gold" one (although mine says 2450 mAh) and I'm using it for 2 days on HTC DoubleShot (details HERE)
Compared to my original stock battery it certainly is of larger capacity and after second charge it got me thru whole day with more than my usual usage (again - more details in the thread linked above).
If you don't mind to chime-in and add your opinion or thoughts to our thread it would be very apreciated, because as of this moment I am the only one trying this battery on our phones (the HTC DoubleShot aka T-Mobile MyTouch 4G Slide) and the more the merrier...
TIA!
