I'm on the hunt for a Nokia BV-5JW battery. 

My previous experience of buying similar items off Trade Me and one or two other places has been disappointing. The last time I bought a new cellphone battery I ended up buying one off Vodafone after a couple of duds from other places.

Vodafone don't appear to have this model battery. Battery Champion have them. Does anyone have any experience with Battery Champion or can recommend another supplier?

Thanks.
