Good news for all you PSP owners. It looks like you will be able to use your PSP for a longer time.
A company blue Raven says they have a battery that can last from 8 to 15 hours.
heres a description.
"The battery comes as part of a rubberized, five-ounce half-shell that the PSP slips into easily, leaving the back of the device encased in a manner that offers a comfortable, balanced grip. It was a bit of a squeeze, but the enlarged PSP still fit into the zippered protective case".
It does come to a cost though, $99 dollars.
