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: http://data.energizer.com/PDFs/490.pdf 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): http://data.energizer.com/PDFs/455.pdf And a few folks still offer the monster 510V NEDA 741 (Eveready 497) photoflash battery, composed of a whopping 336 #118 cells in series! http://data.energizer.com/PDFs/497.pdf I think I'm a battery geek. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
