[AT] desulphating battery chargers

[Larry D. Goss]

Huh!?  Since when?  A discharged battery has a weakened mixture of
sulfuric acid and water in it, but JUST WATER!--I hardly think so.  In a
discharged battery, both electrodes are lead sulfate.  The sulfur comes
out of solution from the acid so that the acid becomes weaker but you
most certainly have no guarantee that the amounts of lead and acid are
so precisely balanced that you end up with pure water.

Gimme a break!  The chemistry just doesn't work like that.

A  fully discharged batter has only water in it the acid is in the
plates 
that's  how they work when you dump the water and replace with acid you
will 
increase  the amount of acid in the battery to a dangerous amount. In
other word 
it is not  recommended to do this I know have seen a lot of people do it
but I 
have also  seen batteries that will smoke and smell of acid when being
charged 
from the  vehicle.  Most batteries quit because the cells flake off as
they 
are used  this is why there is a large open space at the bottom of all 
batteries. Marine  batteries have a larger space because of the rocking
of the boat. 
Sulfated  batteries are those that have been left a long time without
any 
discharge or  charge just left on the shelf to get all sulfated. You
don't find 
this very  often that's why you can only find a few batteries that will
cleanup 
with your  desulfating charger.
