A product called VX-6 will rejuvenate aging car batteries for a short 
time (given the battery-failure mode for which it is effective). I 
don't know its chemistry; it really works, but only ONCE per battery. 
I intend to try it when my 8-year-old Wheat Lamp battery deteriorates 
further, make before/after measurements, and publish the results in 
_Speleonics_.

Battery manufacturers (and manufacturers in general) seem to have 
become more secretive in these litigious (sp?) times. See the catalog 
of Lindsay Publications Inc. [PO Box 12, Bradley, IL 60915-0012  (815) 
468-3668] which features a "lost technology" series of reprints of OLD 
books on fascinating mechanical and electrical things.  Lindsay has 
several books on lead-acid batteries, which discuss design variations 
to optimize high capacity, deep discharge, low internal resistance, 
etc.
