Lemme clarify the battery confusion. The only thing that pandora changes on the battery is the serial number of the battery. There isn't any 'code' in the eeprom of the battery, just information about the battery (i.e. manufacturer data, capacity, serial number, etc). The pandora battery changer just changes the serial number to all 1's in binary. The rom firmware in the PSP reads this serial number when you power it up. If it sees that serial number, it looks for the IPL code on the memory stick instead of the system flash. That's why pandora's 'battery' isn't just a battery. It's a battery and a memory stick. That's also the reason you can't use the battery like a normal battery, because it always tries to load the IPL from the memory stick if you boot with that battery in, which obviously won't work if you have a regular memory stick in. Plus it won't boot whatever firmware you may have installed on your PSP. It just boots the IPL on the pandora stick. Hope this clears some things up.

Let us know Pandora’s Battery

On August 22, 2007, Team C+D released the “Pandora’s Battery” that can convert a spare Memory Stick Pro Duo and battery into a “Magic Memory Stick” and a “JigKick Battery”. The Memory Stick and the JigKick battery couple is called “Pandora’s Battery”. The Memory Stick and battery can then be used to downgrade any PSP of any version or to recover from a brick. To convert the Memory Stick and battery another PSP which is able to run 1.50 homebrew is needed. The Memory Stick can also be converted without using a homebrew PSP by using a Pandora’s battery program, such as Pandora Easy GUI. After the downgrade/unbrick service has been completed, the Memory Stick and battery can be restored for normal usage.
A “JigKick Battery” is a battery with the first adress in the EEPROM chip changed to 0xFFFFFFFF. This unlocks the service mode of the PSP and launches the IPL from the Memory Stick (instead of from flash0). A “Magic Memory Stick” consists of a reverse-engineered IPL and a minimal subset of the firmware 1.50 stored on a Memory Stick Pro Duo. This downgrader can downgrade all firmware versions. The original version is incompatible with the PSP Slim & Lite due to the 1.50 IPL being incompatible with PSP Slim & Lite hardware. However, on September 28, 2007, a version that works on both the old style PSP and the Slim & Lite was released. The new debricker is called Despertar del Cementerio, and is also known as the Universal Unbricker, which was developed by Dark_Alex. Instead of installing firmware version 1.50, it installs a custom firmware.(PSP Battery )
The “JigKick” battery can also be created by lifting the fifth pin of the EEPROM on the battery’s mainboard, circled here. This is somewhat dangerous because it disables the EEPROM entirely, and may have side effects such as overheating if pin 5 is shorted to other pins while desoldering.
The battery that is included with the PSP Slim can also be converted into a “Pandora” battery by using the hardware modification method mentioned above.
There is now a method that will enable users of custom firmware above 3.71 M33 which does not automatically have the 1.50 firmware kernel to create a Pandora battery. This method can be found here.
Though Sony advocates against use of any homebrew, representatives have said that the Pandora’s Battery will not physically harm the PSP in any manner, as this is the same method used by Sony when customers send in their bricked PSPs for repair.
