What is Pandora Battery (Sony PSP)?

Here are some of the information about Pandora Battery I grabbed from the web. Hope it help.

The "Pandora's Battery" as they call it, is just a regular PSP battery. The battery of a PSP has flash memory on it with boot information for the system. When converting the battery for downgrade procedure, the PSP program that we use actually dumps the batteries flash and puts a bin image with official sony firmware e.g:1.50 and some developer code. When we place the converted battery into the PSP it boots and runs the developer code and downgrades the PSP. At this point, they say that the battery is useless. They have come out with an update that will convert the battery back and thats why they dump the flash first. After the PSP is downgraded, if we use the converted "pandora's battery" as ourr power source, it will only run a partial of the 1.50 firmware because of the missing battery flash files. In order to have full 1.50 we must convert the battery back into a normal one.

Beside that, I do found an explanation that Pandora Battery would also be something that could change the power levels going into the system to drop the chip into a debug mode and allowing a more direct way of programming or flashing the main firmware chip.

I hope the explanations are correct. Do give comment if some of you found it is misleading.
