"For those who really need their PSPs to go the distance, Sony today announced the PSP Extended Battery Kit, which is composed of a 2200-mAh and replacement battery doors in both black and silver. The new battery will pop right into old model PSPs and the replacement doors accommodate the larger battery's bulge in Slim models. The Extended Battery should come close to doubling the PSP Slim's usable battery life compared to the battery that's included in the system.
The PSP Extended Battery Kit will arrive in mid-December priced around $45."
