I was wondering if any compartiable BL-5J can be used in the N900? In light of the battery issue experienced by everyone here I've went ahead and got two 1900mAh BL-5J batteries (those are not office Nokia batteries btw) but a bit worried that the extra capacity will damage the phone in some way.

I've had weird issues with my G1 when I had extra capacity batteries installed (such as the battery level displaying incorrectly and whatnot)

Any ideas?
