Default Jim Weir - desulfating battery charger

My travel trailer power converter has an optional microprocessor plug-in
device called a Charge Wizard that would periodically run a desulfation
cycle as part of its battery charging function. Rather than building such a
device, it might be simpler to buy a converter and the power wizard. I did a
little net search on converters after writing the previous sentence and
found the latest model has the Charge Wizard built in and you don't have to
buy it as an add-on. the URL below will take you to it. The converters are
not cheap at $190 but mine is six years old and still working fine(as far as
I can tell) The Charge Wizard starts in boost mode to charge a discharged
battery and when it reaches a 90% charge drops to Normal mode
to complete charging the battery, after 30 hours of Normal mode it switches
to Storage mode which is a reduced charge maintenance rate. Every 21 hours
while in Storage mode it runs a Desulfation Cycle. I'm not a converter
salesman, just a trailer user, but though this might prove to be useful info
for some of you.

Jim, that was an excellent article in last month's kit plane. I'll be
getting the parts together to build one here shortly.

There was also a nice article in Sport Aviation (for a change), that
actually showed how to build something. In this case a battery
desulfator.

The question is, how feasible would it be to combine the two circuits,
making the circuit would go into desulfating mode When the battery is
charged?
