[Shop-talk] Solar car battery chargers

[Scott Hall]

  Wow.  That thing's pricey, but it's cheaper than two new batteries.  
It says it has a constant desulphation phase--can the EEs opine on 
whether that's marketing speak or legit (Randall's explanation is that a 
desulphator stores current then zaps the battery to do its thing).  I 
also don't see anything on that page that says (to a moron--me) that it 
regulates the charge and so won't overcook the battery when it's topped off.

Actually, I'll abdicate thought on this one.  Is that the one I should 
buy?  Better to listen to the guys that actually know what they're 
talking about--I loved this stuff in college, but now I just try to keep 
the smoke in the wires and not electrocuting me.

Thanks.
