I say Bullsh.......
None of the third party batteries can achieve that, it is a total scam, even at that price
Get the one from sony, wich is up to 2200 mah, I have one and it does last longer than the original 1800mah I had, like 2 hours more.
But, if you use the 2200 mah official sony battery on a psp slim with a bigger battery cover of course, you may be able to squeeze out around 10 hours of gameplay,
