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. -- Frank Reid W9KKV @ WA8YVR NSS 9086F reid@gold.bacs.indiana.edu
