Looks as if there's one left at https://www.alzashop.com/patona-pro-...utAutoChange=1 ; f.y.i. From what I've read on this thread it's from a good manufacturer. Sadly they don't ship to the U.S.A. or I'd have bougt it.

Instead, I found a Nokia BL-5J with a stated power equal1430 mAh. It's from ebay. It's advertised as new, original. This is remarkable because the two batteries I have (both similar looking to this one I bought) state the power is 1320 mAh.
