Since the cost of replacement batteries is low, this seems like a worthwhile trade off.

Capacity is settled on as a measuring metric. Hello Dennis, Let’s back up a moment Since at the time there were only carbon-zinc cells, no suffix letters isc other notation were required. We have no document history for this standard.

A single zinc-carbon torch cell. Secondary cells and batteries containing alkaline or other non acid electrolytes. If the document is revised or amended, you will be notified by email. Now we have a standard for charging. The engineers figure out the best way to get the most capacity into the battery and everyone agrees.
