But IS there an internal battery? A quick Google didn't turn up anything. If 
there is one, eventually it'll fail, and in that case the 'net should be 
full of comments, how-tos, and calumnies.

Must be a pretty uncommon problem. After all, who lets their electronic 
camera sit unused for 9 years and then tries to re-use it? I wonder if Nikon 
ever even thought about this sort of thing happening.
