Don't believe voltage changes with load.
Since the battery has resistance as the load increases the voltage will
drop. If the battery had no resistance you would be correct.
My guess is the OP is using a digital meter and is finding he gets
different results since the resistance of the meter is so much higher than
the old analog meters. Of course part of the problem is likely to be as you
correctly pointed out the measured voltage of different kinds of batteries
varies.
Amperage is number to
deteriorate.
Electromotive potential determines voltage. If you open up a standard
9 volt battery you will find 6 1.5 volt batteries in series.
Battery's voltage will depend on materials it is made from. Alkaline
batteries will vary from the standard 1.5 volts of old carbon/zinc
batteries.
