the only places that sold original battery packs were sony stores in klcc, curve and at 1 time, Berjaya times square.
I bought my batteries (all versions from the 1,800 to 1,200 and 2,200 mAh) from there and sold off a few too.
damn....lost my chances to buy from there.

i presume it is at limited quantity(in sony stores),right? how much did you bought out the 2200 mAH stamina battery? which packaging version? us/eu with 2 piece of cover or japan ones with only one cover? i'm curious to know....

guys, afaik battery pack is a good thing to ask tripleB to bring. last time my battery pack been stolen due to house ransack.
ouch... the thief delibrately stole the battery not the psp itself? what an a**hole!
QUOTE(andrewcha)
btw tripleB, check your PM. thanks.
hehe, buying the same thing?
also, here's some tip to psp's owner with
original batteries.
in my observation, psp
always overcharge the battery if using normal a/c adapter charger.. moreover it is hot in there, thus reducing battery lifetime. so if it possible, use sony psp external charger like this one to charge the battery:

helps in detecting fake batteries too!
rant:
sighh....how come vita doesn't have replaceable battery? ok, it CAN be replaced (with some tinkering) but no official battery packs like this one? if the battery dies out, then what? i HAVE to buy a NEW vita?
actually, how much does sony charge (for replacing the battery) if the warranty has expired?
