Typically their capacity is labeled in amp-hours. You have to know your
devices to know if the voltage difference between different battery
types (Which ranges from 1.2 to 1.7 for nominal-1.5 AAA/AA/C/D cells,
and may be lower under load) is significant or not, and in what
direction. A lower-voltage battery in an incandescent flashlight will
last longer but not be as bright. No idea how it shakes out for LEDs,
motors, or complex electronics. Some devices may not be operable at all
below a certain voltage, and of course the voltage reduces over time as
the battery is drained.

There are just too many variables, and even the nominal amp-hour rating
assumes a certain discharge rate.

And of course, for rechargeable batteries there are even more variables;
but there what you're buying isn't power.
