After a lot of research and experimentation I have come to learn that the sentence "This is a 1.5 V, 2800 mAh battery" is entirely a lie. (i.e., the potential difference between the terminals of a battery changes over time and the shape of the graph is dependent on battery chemistry, ambient temperature and current draw, as is the useful energy capacity.
