Which battery should I buy for my PSP?

Thanks!

But I guess you haven't tried it yourself?

What is the original battery in the PSP-2000, is it 1800mAh? I opened up my PSP and it said it's a 1200mAh.

So by using simple math I would get about 8-10 hours of gameplay with a 2400mAh battery, since I have 5 hours now.
