It sounds like you know the history. Why are zinc-carbon batteries called 'heavy-duty'?

- tanzam75 12y agoSorry, I gave the wrong chemistry. The carbon-chloride battery is labeled as "heavy-duty," because it has greater capacity than the carbon-zinc battery ("general-purpose"). When alkaline batteries were invented, the older chemistry continued to be sold as heavy-duty. This leads to the strange situation where the heavy-duty battery has less capacity than the other batteries you find on the shelf.
