I have a wireless temp sensor module that currently runs off a 18650 battery. I am eventually going to get some PCBs made for it and I'd like to reduce the size of it to make it as small as possible so am trying to decide what batteries to use. I think the 3xLR44 or a LIR2032 would be a good choice…

LIR2032 / 3xLR44 for wireless sensor

2 LIR2032s arrived this morning so swapped out my 18650 for one to try out. Working perfectly so far. Be interesting to see how long it lasts.
