Battery Analysis Spreadsheet.



I've put this battery spreadsheet together for my Zappy List.  I listed all Long
Batteries, though most of them are not useful for EV applications.  This has comparative
information for Longs, Hawkers and Optimas.  It's a work in progress.

Note the Long WP22-24NE,  24V 22AH SLA AGM Lead Calcium battery with an energy density of
114 wh/L and specific energy of 43 wh/kg.  Nothing else comes close.

Has anyone put a similar spreadsheet together?

If anyone would like to take this spreadsheet as a starting point and add more data to it,
please do so, and let me know.

Note: you may have to register with egroups to get access to this file.  It's a simple
process and you won't get spam.
