Why is it that rechargeable batteries state the capacity,eg., 2500 mAh but
the 'use once' sort don't?

I suppose its a selling point and also indirectly an indication of
quality on a rechargeable - they are probably also bought by more clued
up users.

Dry batteries also have a stated capacity - but often only on the makers
data sheets rather than boasted on the side of the battery.

Note the discharge characteristics will be different - you may not be
able to draw the full capacity from a dry cell in quite such as linear
was as you can from a rechargeable.

Some of the figures are available though:
