The message
from Dave Fawthrop contains these words:

Until Alkaline battery manufacturers state the Ampere hour capacity on each
battery, I will believe that they are all the same and buy the cheapest
available.

Their argument against doing this is that the effective Ah rate of each
cell differs at different discharge rates and that comparing like with
like wouldn't be possible.

I suspect having two figures, C1 and C10 rates, for example, might be a
way round it but there's pleny who'll say it's too confusing.
