   How do the electronic desulfating chargers work?  Can I fake it with a
   555 timer and accumulator triggering a SPDT relay from ummmm... my
   car's charging system through the 25A cigarette lighter?  I was
   thinking driving it around would help for agitation.  Just anchor it
   in the trunk for a week or so of commuting.
   Or, you know, I could buy the right tool.  I've always been curious
   how it works but I heard it was a square wave of high amperage pulses
   , 5A to 12A?
