3. They are different thicknesses.

If your device uses 2-2016 batteries it's running on 6 volts (2-3v batteries stacked). A single 2025 or 2032 is 3 volts, not the 6 that your device probably wants. A 2025 or a 2032 are physically the same diameter, but thicker than the 2016 and thus have more capacity (will last longer than a 2016 when a single button cell is used). The 2032 is 2x the thickness of a 2016, but only 3 volts.

There's a decent chart of battery sizes and (some) characteristics at http://en.wikipedia.org/wiki/List_of_battery_sizes

Hope this helps!

Same size, same voltage, different capacities krispos42 Mar 2012 #10

Thanks. I think I'm getting it now.So no doubling up of the THICKER ones to replace the thinner ones UTUSN Mar 2012 #11

Yes, you'd be getting more endurance from the same voltage. krispos42 Mar 2012 #13

O.K., your last sentence clinched it for me, totally. Thanks. UTUSN Mar 2012 #14

Basically it doesn't matter. Size, maximum current, lifetime, total charge. saras Mar 2012 #17
