Electronic – the recommended fully-charged voltage for NiMH AA batteries

batteriesdesignspecifications

I have done research on different batteries and cannot find a maximum OR minimum voltage to keep NiMH AA batteries within. It seems that typically battery chargers will measure the negative voltage CHANGE or the temperature, but are not designed to hit a certain voltage limit.

I have seen some claim that 1.5V is a good upper limit and 0.9V a good lower limit, but my question essentially boils down to:

What do most electronics want and expect from the AA batteries they run on?

For reference, here is the datasheet I found for Eneloop AAs

Well the very first hit when googling "NiMH AA battery data sheet" gave me this information: -

If different batteries are specified at different levels then there is no generic upper and lower limit.

What do most electronics want and expect from the AA batteries they run on?

Most people regard the voltage output as being 1.2 volts nominally.
