I'm no battery geek, but that last pdf was fun to look at ;-)

I used to work for one of the major battery producers in their R&D
facility and because I am rampantly curious, asked many questions
You sound like me!
This is a long-winded explanation that says, if you assemble a 90V cell,
use the chemistry they did back then with the type of cells they used back
then,
There is some data lying around. A NEDA 204 (IEC 60F40, Eveready 490) 90V
battery, uses 60 #135 cells (LeClanche-Manganese Dioxide) in series.
Unfortunately, I don't know the specs on an F40 or #135 cell, so I don't
know the milliamp-hour capacity. Here's some data I found:

Exell make an alkaline version of this battery (for $34.50), but they don't
seem to offer any specs on it. Perhaps I'll ask them.
Data on the "skinny" 90V battery I had is even more scarce. It's a NEDA 214
(Eveready 479). I don't have an IEC code and I don't know what kind of
cells it was built out of (I'm guessing something like their 140mAh #118
cells or 200mAh #118P cells). I took it apart, and it was physically just
ten 9V rectangular batteries in series, all in a cardboard wrapper with snap
terminals on top.
Have any clues or data on these old 90V batteries?
Apparently, Union Carbide/Eveready still makes the old 455 (NEDA 202) 45V
550mAh B battery (30 #130 cells):

And a few folks still offer the monster 510V NEDA 741 (Eveready 497)
photoflash battery, composed of a whopping 336 #118 cells in series!

I think I'm a battery geek.
