I got one of these from Hong Kong - wished I hadn't wasted my money! - the charge is useless at best - tried to watch a UMD film on it - couldn't even make it half way through (on a full charge!) Whereas the original one lasted until the end of the film before dieing on me.
The battery just sits in a corner gathering dust now...
I would recommend getting a genuine $ony one (2200 mAh) - these do actually last longer!
