I submitted my question regarding using the equalize (desulfating)
mode on my Statpower with lead acid house and Optima chassis
batteries. Here is what Ann-Marie sent me:
Yes a lead-acid equalizing cycle can damage sealed batteries. If
left on, the Combiner(s) would apply those voltages to the Optima so
to be safe, they should be disconnected while equalizing.
I'm not sure which combiner you are using but later models have a high
voltage shut off. This can be connected to the sealed battery to
protect it from high voltages that could come through the Combiner.

I think you are confusing de-sulfators and sulfate prevention.
De-sulfators put a high frequency high voltage spikes into a battery in an attempt to remove and recombine sulfate back on to the plates and acid. It is as much a repair function as it is a prevention function. This action is NOT going to go through a combiner.
OTH, the sulfate prevention is the action that we get using the PD converter. IN the PD (and some others) it is a feature that once every 21 hours raises to the charging voltage to a higher than normal DC voltage to stir up the electrolyte. This DC voltage stays there for 15 minuted and then goes away. This action will operate through a Converter.

No confusion here Ken. I was worried about setting the Statpower unit
to "Equalize" with the combiner installed. That was the question I
asked Yandina, you saw the answer.
