I want to have a spare battery on hand just in case I need the extra juice.

Does anyone know if the Nintendo shop in Mid Valley sells the battery? I did a search and couldn't find it anywhere except on Nintendo's online store, but they only ship to the US and Canada. I also read somewhere that the battery is only available from Nintendo direct.

I don't want to buy one of the third party ones - I've heard they're crap and last less than half as long as the original battery.

So has anyone who's been to the Nintendo place in MV seen a DSL battery there?
