However, if you leave the button cell installed it drains to empty within a few months or less. Do you know for sure your example scale doesn't in fact drain its battery while in standby?

I also have cheapie but mine have on/off button. "Turning it off" reduces power usage by about 20%. Like, what's the fucking point of "turning off" |O

Ahah, yeah they're not all created equal. I've owned a cheap digital caliper that would just deplete batteries in a few weeks when off.
OTOH, I have a Mitutoyo one that I've bought a few years ago. Original battery is still good and I haven't changed it yet.
