it's very simple no need to open up the battery to make pandora battery (hardmode)  
yes there is other way to determine the battery is ori or fake ,
post here  nah........... maybe i will post on play-beyond.net  but tell you this you need to see it very very carefully.

hi Guys

I have a problem with my FF7 crisis core save game. This is the scenario

I actually have 2 FAT PSP. And im using UMD original ff7 crisisCore

I played ff7 on my 3.52m33-3 psp saved it. Then take out the memory card and insert it into my other psp which is a 3.71m33 psp. But when i want to load the saved file, it says corrupted.

HELP~!!!!!!!! im almost finished with the game, and now my save file is corrupted!! I sold off my 3.52m33 psp..tats y im stuck.

Can anyone help me with this? How can i recover it? OR is it that different firmware save files are not inter-exchangeable?

i know the voltage in M'sia.....but i going to ask my friend help me buy at amazon.com since she comming back soon from US...........the external charger the one that use to charge battery only original made by SONY.......issit will suite to use in M'sia???? help meeeeeeeeeee
