Bad idea. If a silver oxide battery goes below 30% charge, there will
be about a 100mv step increase in terminal voltage:
I've seen the step in my cheap Chinese digital calipers, where I need
to re-zero the indicator when the cell voltage crosses the transition.
Of course, the alkaline batteries are somewhat worse, where I need to
re-zero the calipers nearly every time I use them.
