2032 and 2025 are literally the dimensions of the battery. A 2032 is 20mm in diameter, 3.2mm thick, and a 2025 is slightly thinner, at 2.5mm thick. They usually both have the same voltage (3V), and assuming they fit in the case, they are interchangeable.
For my scale, I accidentally bought a pack of thin 2025 batteries instead of the thicker 2032 ones.
I couldn't get the scale to work as it was too thin. So I used 2 batteries stacked. Scale works.
Is there another way to get it to work with just one wrong thin battery? Feeding it 6V can't be good for it.
IOW: What could I use to pad the thinner battery?
