I need help with the PSP battery!

Hi,

I recently just got a PSP 3000 that came with the 1200mAH battery, which to tell the truth doesn't last all that long. I was just wondering if the 1800mAH battery works with the PSP 3000 and how much longer it lasts compared to the 1200mAH battery?

Thanks if you can help.

P.S. I don't want to get the 2200mAH battery ( I'd like to keep my PSP "slim" ).

I think it's a pretty straight forward equation...if 1200 gives you X hours of gameplay, the 1800 will gives you X+1/3X. So, for simplicity, if the 1200 gives you 2 hours, the 1800 will give you 3 hours. And the 2200 will give you something like 3.75 or whatever. I could be wrong, though, either in my assumptions regarding the formula or in my actual math.

Anyway, the Logitech hardcase for the 2000, which also fits the 3000, is built to accomodate the 2200 battery. With that being the case, you'd never notice the extra size, as it all fits inside the case.
