I know it doesn't exactly answer your question, but check out your local Batteries Plus. They usually don't have a lot of variety, but they'll likely have something that's on the approved list. Also, if you register with them as a corporate account (all it requires is a phone number, and they've never called me) you get a rather large discount... I want to say it was almost 3 for the price of two last time I went! At any rate, that should save a little bit on shipping!
