RJT> JE> I'm getting old and my memory isn't what it used to be, but seems
RJT> JE> that the A battery was round, about 2-3" in dia and about4-6" tall.

RJT>Never saw one,  so I can't comment on the size.

That one turned out to the the #6 Battery. As I remember it was popular
with model plane enthusasts for the engine Glow Plugs.


RJT>The size designations were one thing,  but I thought that the functional
RJT>designations were a whole different thing -- maybe not?  "A" was filaments,
RJT>was plate supply,  and "C" was grid bias.  I remember some old battery tube
RJT>radios but I don't remember ever seeing one that used a C battery.

It was replaced with a voltage divider.


RJT>Oh,  and there was one weird one I ran across one time -- I wanted a 6V bat
RJT>and this place sold me a unit (I can remember that it had the "Burgess"
RJT>coloring) that had five screw terminals across the top and a wire coming ou
RJT>one top corner -- giving you a choice of 1.5, 3, 4.5, 6, and 7.5V!

I rembember those. But don't recal lthe most common use.


RJT>I thought AAA was more recent,  and AAAA even more so.

The AAA and AAAA are more rencet then the AA. In fact back in my Radio
Repair days in the late 40's they didn't even exist. They are a produce
of later year minitarizuation becauwee of Intergerated circuits.
I find it increadable that they have Radios built in to fairly small
headsets.


RJT>I remember doing that for all sorts of reasons.  The rods out of D cells we
RJT>handy for electrolysis,  for example.  And there were some other projects y
RJT>could do that I'm not remembering at the moment.


The Carbon Rods from the #6 Battery was also popular for various uses.
Including the already mentioned Welding.
