SuccessHK have today released what could be the bargain of the century for PSP Slim owners, the 2200MAH Battery (2xthe original power) is a staggering USD 6.37 around £3

What a killer bargain

I might get this...

it wont be a bargin when it; leaks battery acid / doesnt hold a charge after like 3 uses / or in most extreme instances , explodes...

is it made in china?

if it is, it might poison me with lead. :|

I have one of these. They hold a reasonable amount of charge (approximately the same as the original Sony battery) but don't report their charge state properly to the PSP, so it will crap out in the middle of a game with no warning.

Oh I just realized as well its for the slim
