So when my Nissan's remote started to act up I tried replacing the CR2025 with a CR2032 as they are both 3v and appear very similar in size. (see comments by others for size differences) Anyway, the CR2032 works great as a replacement for the CR2025.

He managed to install the thick one where the skinny one was called for. I've used a skinny one in place of a thick one before, but you have to be careful that it will still make contact. Sometimes the spring doesn't have enough compliance. It's even worse when multiple cells are stacked. -- Rick

I had ocassion to tear apart a CR2032 cell: <http://802.11junk.com/jeffl/crud/CR2032-disassembled.jpg> Note the mottled looking white Lithium smear on the anode terminal on the right. Over a period of several days, the somewhat clear lithium oxidized into a white coating. Notice that the crumbling MnO2 cathode is somewhat thicker than necessary. When I tore apart a CR2025 (sorry, no photo) it was the same as the CR2032 but with a slightly thinner MnO2 layer. It might save some money to use identical components. I haven't run discharge tests yet (I have a West Mtn Radio CBA-II analyzer) but I wouldn't be surprised if the CR2032 and CR2025 were identical capacity. If you look at the discharge curves, the "Discharge Characteristics" graphs are identical. <http://biz.maxell.com/files_etc/9/cr/en/CR2032_DataSheet_12e.pdf> <http://biz.maxell.com/files_etc/9/cr/en/CR2025_DataSheet_e.pdf> -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558
