You'll need to use pandora's battery.  The procedure varies depending on whether you have a slim or phat psp.  Here's a couple of links to get you started.

I've never had to use it as I downgraded my phat psp with the original GTA:LCS downgrader from 2.5 ofw.   But if you're willing to read up on it I'm sure its not that difficult.  There are plenty of forums about that give step by step intructions.
