What is the difference between a 2032 battery and a 2025 battery?



CR2032 CR2025



The CR2025 and CR2032 are both 3V button cells, have identical diameters but the 2032 is 3.2mm thick while the 2025 is 2.5mm thick. With just 0.7mm of difference, for as long as either fits in the battery compartment, they can be used interchangeably with minimal effect.
Do note that the 2025, being the thinner of the two, will have slightly less storage reserve and will typically not last as long as a 2032.
