It seems that the meter's usefullness would mostly be of use for comparing
readings of nearly identical cell/battery types, but otherwise just a tool
to gather readings which could be useful for statistical data (which may or
may not be useful after many entries).

It might be good if you buy second-hand batteries replaced on a
schedule. To test and accept/reject new ones you'd need the battery
manufacturer's spec sheet.

I measure a battery's remaining capacity as how long it will run this
laptop. When the screen brightness changes the inverter has just shut
down.
