I was being a little bit tongue & cheek since the number of electrons in the battery really doesn't change with the state charge or current. It mostly related to the number of protons in the battery.

My real point was internal resistance is really a measure of the batteries ability to supply current under particular set of conditions. It says nothing about the actual efficiency of the chemical reactions going on in the battery. Others, who know a lot more than I do about batteries, have posted in effect that the amount of useful energy in the battery changes with the current or power. That matches my experience.
