I have a few remotes I rarely use and storing alkaline or expensive lithium cells in them seems a waste for an occasional use. I was thinking of using 1 or 2 2032 lithium *coin* cells in them (in parallel if more than one). I can get these batteries for about 20 to 40 cents each and not worry about leaking or buying expensive AA/AAA cells. The remote for a portable dvd player uses a 2025 cell in it so which is what gave me the idea.
