RJT> TW>  I had inadvertently left out the "N" battery. It is a popular one
RJT> TW> for  Pocket Pagers. But it is of reliatiavely recent introduction
RJT> TW> compaired  to that "A", "C", "D" series of cells.

RJT>I remember running into it way back in 1974,  so it ain't that recent...

But I don't recall them in 1944


RJT> TW> A quick check of The Radio Shack Web site shows that they omnl;y
RJT> TW> carry teh Alkaline "N" battereis under cat # 23-023
RJT> TW> But NiCAD and NiMH rechargable "N" batteries are avaialble from
RJT> TW> other sources. The Standard "N" cell is 11.5 MM Diameter and 28 MM
RJT> TW> tall. There are two variations. The 1/3 "N" at 10.8 MM Tall and the
RJT> TW> 4/3 "N" at 44.5 MM Tall.

RJT>And then there's one that's roughly the same size as the N cell but puts ou
RJT>12V!


BUT that WOULD not "By Definitioon" be a "N" Cell, but simply a 12 Volt
Battery. ALL the cells in the series I am talking about, A, AA,
AAA, AAAA, SC, C, D, F, Super F, G, J, N, 6 all have a nominal voltatge
of 1.2 to 1.5 volts depending on their Chemical Composition. They are
individula Cells. Something with 12 volts, even if it was close to the N
cell size, would not be an "N" CELL. But a stack of cells, most likely
without any official designations, to make up the 12 volt stack.
