I was referring to open circuit
voltage which is how batteries are usually measured since "under load
voltage" is obviously dependent on the load.
Actually, to nitpick, dry cells at least are properly measured under a
light load, because as they age, they develop higher internal
resistance. Measuring them with a high impedance voltmeter will
suggest they're good when they're not.
