RJT> TW> batteries. They are in Increasing size order, AAAA, AAA, AA, A,
RJT> TW> SC(Sub C, C, D, F, Super F, G, J, and #6

RJT>I've also seen Sub-C designated as "Cs".  And now that you mention that "#6
RJT>remember that's what those big ones were.  I wonder what happened to #1 thr
RJT>#5?

Some C's are called Wrongly sub "C" becasue they are 1/2, 1/3 etc. BUT
there is a Standard Sub C catogeory that is a 26 X 46 MM battery. It
comes in height veriations of 1/2, 3/5, 2/3, and 5/4.
The Sub C is a 23 X 43 Battery with varaitions in height of 1/2, 2/3,
4/5, 5/4, and 4/3.

RJT> TW> I also found out some other interesting Size Data.
RJT> TW> There are 7 Variations(same Diameter shorter Height) of the "AAAA"
RJT> TW> Battery, 20 Variations of the "AAA" battery, 9 Variations of the
RJT> TW> "AA" Battery, 7 Variations of the "A" battery, 7 Variations of the
RJT> TW> Sub "C" battery, 4 Variations of the "C" Battery, and 4 Variations
RJT> TW> of the "D" battery.

RJT>My experience is that those are given as fractions,  like "1/2C" or "2/3Cs"
RJT>similar.  Is this what you were bumping into?

Thatio s correct.

RJT> TW> Some sizes also come in "Flat" Versions, Same MaH as it's counter
RJT> TW> part except for a rectangular shape instead of round

RJT>Rectangular packages take up less room for the same amount of volume,  but
RJT>probably cost more to produce.  Was that indicated in the prices for these?

Definatly so.  Typicaly about Three times more.

RJT>I was astounded last night,  while scrapping some parts off boards,  to pul
RJT>one item that turned out to be a lithium battery -- roughly the same diamet
RJT>as a AA but only about 7/16" long,  and it had tabs welded to it to mount t
RJT>the board -- and it still tested good!  This was off a board that came out
RJT>an old terminal that i scrapped that had been sitting in storage for some
RJT>years...

RJT>Got any particularly good sources of battery info?

Only general basic information. and then mostly NiCAD, NiMH amd Lithium.
it is the WEeb site   www.powerstream.com.  They are a wholesale buyer
of battereis from China. On the Left side of their main page check
click on the link to "Technical Recources". Very enlightening without
going into "Brain Overload".
IF one wants to get more detailed information there is tons of Papers
etc on the Net. Just do a Search for what you want.
