I'm looking for assistance from someone living in Japan who can buy an item for me (PSP 3000 Extended Battery with Pearl White Battery Door, PSPJ-15018) and ship it to my U.S. address since I am unable to do so directly. If you or someone (trustworthy) you know can help, reply or PM me and we can work out the logistics. Thanks in advance!
Also, does anyone know if I need to worry about using a Japanese battery in a U.S. PSP? They're both labeled 3.6V 2200mAh, so I would think it's the same thing; unless there's a subtle electronics difference I'm overlooking/unaware of, I would think I could use it fine. (I actually want it more for the battery door, so if it's a problem I can always get a U.S. battery.)
