PSP Battery Pack in Old Fat PSP?

[cereal_killerxx]

About a month ago, I bought an old fat psp from my friend for about 70 bucks but the battery life doesn't last as long as I had hoped :cry:. Then recently, I heard about the new battery pack that came out and how it would double the life of a slim psp... but what about the fat psp? How much extra juice will I get from it if I stick it in the brick sized version?

the battery for extra life is for fat psp. I think it is like extra 20 or 30%

Make sure the volume is off when you don't need it or at the lowest setting you need it at. Also make sure it's at the lowest brightness screen setting (unless you need it brighter).,

It's not that much better than the regular batteries. Make sure you follow MasterSprtn117's advice and don't forget to turn off the WLAN switch if you're not getting online.
