Help with a fatboy psp 1001

[chemicall]

ok thanks alot everyone i'll pandoraize the phatboy battery with hardmod. Although my friend probably won't want his psp back when he hears he has to buy a new battery, but he didn't really care, if I fixed it he was just gonna pawn it back at the pawn shop he had bought it at I'll just toss him a few bucks for it....as i did get a really nice good sized PSP case out of the deal. OH yeah and his battery is already drained, not been used or touched in over about a year.
