Judging from your heading, though, you want to know the difference between a CR2032 and a CR2025 battery. The only thing you can count on at all is size: the CR2025 will be 2.5mm thick, instead of 3.2mm thick. There's more room inside the bigger battery, so the CR2032 will _probably_ have more capacity and slightly higher current capability, but the battery manufacturer is free to put whatever they want inside the case: they could even use the CR2025 innards in a CR2032 shell, to save production costs. If you need to know how a battery is going to perform in a specific application, your best bet is to look at data sheets from specific manufacturers (the good ones do publish these; some even publish accurate ones). Use the data sheet to verify that the battery will or won't do what you need. There's probably more advantage to be had by buying a really good name brand CR2025 over a cheap no-name one than there is to be had by going from a no-name CR2025 to a no-name CR2032. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

The 20 stands for a nominal diameter of 20 mm. The last two digits define the thickness. CR2032 -> 3.2 mm CR2025 -> 2.5 mm

Well... one used to be able to refer to matchbook covers, and adjusting one's points and such antiquated "skills". Sure glad I quit smoking back in '87. Never looked back.

I do it all the time.... so to speak. -- Rick
