MM> TW> Forst how many rembember the Old Home Battery operated Radios? My
MM> TW> grandmothers Farm House i nMissoury still didn't have elctrical
MM> TW> power in the 40's. Those Redios typicaly used more then one Battery.
MM> TW> There was "A" batery, a "B" battery and
some times a "C" Battery. How
MM> TW> many can rembember their uses and what are they?

MM>The "A" cells [batteries] powered the heaters, and the
"B" batteries provide
MM>the HV for the plates of the tubes.

MM>I'm not familiar with the "C" battery, but there was
another one that combin
MM>the "A" and "B" within a single package with a
multi-pin connector.  Maybe t
MM>was a "C" battery?

Well you get an "A+". The "C" battery used in some
battery operated
radios was for the Grid Bias. Those that didn't use them had a voltage
difvider setuyp to provide the Bias voltage for the grid. I rembember
the combo "A"/"B" batteries. Depending on the set they7
were used with
and the volume levels one or the other could die first. Some perfered
the seperate batteries.

MM> TW> Also how many rembmber the "F" cell in the current series
MM> TW> designations of "AA", "AA",
"AAA", "AAAA", "B", and "D". They
are
MM> TW> currently being sold by the way sometiems called by another name.

MM>The "F" cell is a longer version of the "D" cell,
and a set of four "F" cell
MM>in a rectangular metal can is what is known as a "6 Volt Lantern
Battery".
MM>There are probably eight "F" cells in the 12V Lantern
battery used in portab
MM>fluorescent lights, but I've never taken one of those apart.  The
"F" cells
MM>also have other industrial uses.

Another "A+"
The most popular application for the "F" Cell was
"Lantern" Batteries
In my looking arround for the "A" battery(which I never found) one here
reports to be using I ran across NEW single Cell NiMH "F" batteries,
Soemtines called "Long D" batteries. They were 11000 MaH units.
Unfortunatly I forgot the price. BUT I was just found it interesting
that Single Cel "F" batteries were avaialble.
And I also was amased that Dry Cel packs were still avaialble up to 510
VOLTS. Those were packs for Professional High power Quich recycling
Flash units as I recall.
BUT it was a nistalsia trip seeing all the old voltages I rembember,
22 1/2, 45, 90 etc
