Can you turn a Pandora Battery back to a normal PSP battery

That depends how you have made it into a Pandora Battery. If you did it with a soft mod i think you can turn it back, but not with a hard mod. Oh and i recently found out this interesting fact, the Pandora Battery only displays a green light and blank screen when plugged in right? Well what you do is take it out, plug in the charger, turn the psp on, put the Pandora Battery in and unplug it. The battery now works...kinda.
EDIT: If you have done this with a PSP Slim battery, all you have to do is draw back the line you cut making the Pandora Battery. Don't worry, Graphite won't damage the Battery Motherboard.
