I've found the heavy duty cells don't last
very long -- in use, or in storage.
In use they provide high current for a short time - not very good for
low current use like electronics, but pretty good for high current use
like toys and flashlights.


The articles I've read say pretty much opposite
of what you wrote.
The "heavy duty" carbon zinc Chloride battery is a different animal
than the old zinc carbon/manganese dioxide LeXlanche battery and puts
out about 3 times the capacity, longer life, and less likelihood of
leakage

They have a longer shelf life, but a lower output/in-use life than
alkalines.

I've found for things like flashlights that sit most of their life but
need to work when you need them, Carbon/zinc chloride batteries are
best. For things that are used every day - low current/light duty use
like clocks and remote controls alkalines are better.

Just my experience. And yes - a fresh alkaline will outperform a fresh
"heavy duty" battery when it comes to hours of output from a
flashlight - but put that flashlight away after half an hour of use
and go back to it a year later - - - -
