better left unasked.

Often I would suspect because some devices cease working before the
terminal voltage used in the capacity calculations is reached.

I have recently had a set of Energiser Lithium AA cells in a camera. They
lasted *far* longer than 'ordinary' alkalines which I usually use. Maybe
they are sufficiently good to be worth paying their hefty premium? But I
do wonder how much is simply loss of voltage rather than actual energy
content.

You should be using NiMh rechargeable in most cameras.
The cameras have high discharge currents and alkalines can't keep it up.
