How to Hardmod a Slim Battery Safely

[Gandalf]

[Guide] Making a Slim Battery into Pandora Battery(Hardmod)
The key to success on this is PATIENCE and TAKING YOUR TIME.
Warning: There is risk of severe burns and possible fire or explosion if the internal battery cell is punctured.


Materials List:

Small sharp knife(eg. X-acto knife, hobby knife, box cutter)

Small screwdriver

Small, thin, but tough, non-conductive piece for prying(eg. guitar pick)

Regular pencil

1200 mah Slim battery


Notice the line that goes around the perimeter of the battery, this is where the 2 halves come together and where we will cut.

Take the small knife and start scoring around the sides along the line, not heavy pressure but enough force to cut a small line in the plastic. Continue with this for many passes, probably 10 to 20, cutting a little deeper with each cut. Be sure not to enter into the battery at any time with the knife more than a couple of millimeters.

After a good scored line has been cut, try to insert the screwdriver into one of the long sides of the battery. Not too deep just enough to separate the plastic a little and get a crack started.

Once you have a little separation started use the guitar pick or other firm non conductive material to gently pry the case open. If it is not cooperating you may need to score the sides more to help with the case separation.

This is what you will have once you get the case open and the circuit board flipped over.




In the zoomed in part of the above pic the is a red circle saying to cut here. Take the knife and make as small of a cut as possible across that silver line in the middle of the circle. Make sure that it is deep enough to sever the entire strip, but as narrow as possible.

The battery should now be in service mode. Fold the circuit board back into position and put the 2 halves back together using some tape to hold the battery together.

To test:

Remove any memory stick from the PSP and place battery into PSP. Without touching the power switch the power light should come on by itself, the screen will be black. If this happens you now have a Pandora Battery for the slim, by the way this Pandora Battery will not work on a Phat as Slim batteries will not power a Phat.

While the battery is in service mode(Pandora) it will not work as a regular battery. To start up the PSP you will have to plug in the AC adapter first and start the PSP up then insert the battery.

To convert the battery back to normal mode simply take a regular pencil and rub across the cut that you made in the line filling the gap in with pencil lead(pencil lead is conductive and completes the circuit reversing what you just did). If you need it to be Pandora again just erase the pencil lead from the gap and it's back into service mode.

There are some new slim batteries that look the same on the insides but Sony has made come changes that make them unpandorable. These changes applies to new slim batteries within the last 6 months or so.

but gandalf why you have to open the battery? you can program your battery through software right?

yes, you can do that. it's called "soft modding" the battery. but in order to do that, you need a psp that's already on a custom firmware to run the program.

as 95% of the people trying to make a pandora's battery don't have a custom firmware installed on they're psp's, then this is one of the options on how to mod the battery.

I just wanted to add, that this a fantastic guide and is a MASSSIVE help to me.
Took me about a hour and a half, and I got electrocuted only once lol

But all works fine, much appreciated ^__^

Thank you!
