Hi Guys,i have a B640WC casio, when i opened the cover i see that the original battery is CR2025, i wanna know what will happen if i replace the battery by CR2016, Thanks.

It will be absolutely fine if it fits but the battery will deplete sooner. The last 2 digits in the battery code represent the thickness (1.6mm vs 2.5mm). This affects the capacity. All other specs are same. For example I shoved a CR2032 in my W-800H even though it supposed to take a CR2025. With that the “10 year battery life” advertised by my W-800H should become almost 15.
