Example, blood pressure monitor electric motor won't operate at <1.4 V. Other devices with good regulation circuits, e.g. better LED flashlights, compensate and are happy with NiMH.

It's actually more complicated than this. No AA battery puts out a constant 1.5VDC for very long and the higher the current draw (strobes, flashlights, electric motors) the more a NiMH will outperform an Alkaline battery in terms of both higher voltage output and mA hrs. The one place Alkaline still perform well is in TV remotes or Multi Meters where the current draw is very low. Still it puts the test equipment at risk if an Alkaline battery leaks and damages the meter.
