Instructions
Select the Pandora Installer application from the gaming menu. If you just recently installed it and do not have a PSP game in the disc drive, it will be on the top of your gaming menu.
Select the "Battery Options" page from the Pandora Installer menu. The menu will look like a simple text file with multi-colored fonts.
Select "Make Battery Normal" from the "Battery Options" menu. Wait as the Pandora battery you have inserted in your Sony PSP is turned back into a stock-functioning PSP battery.
Select the "Back to Mainmenu" option on the "Battery Options" menu and select "Quit" to finish normalizing the PSP battery.
