It simply adds more playing time
If you noticed that your psp slim and lite is always running out of juice in a couple of hours, this is "the solution".

great item
this is the best place to buy a psp 1000 Battery.

You must buy it
I got another four ours of fun. It's something everyone must have !

Double the time double the fun
As title said. It's a a bit big but can give you a better grip on PSP. Still,two times the playing time is wort it all. A must get for PSP owner.

A Necessity For All Users
This is a great product, it's definably worth the extra thickness for almost 8 hours of battery life, I already had one from my old PSP but this has the extra cover to suit the slim & light
