My old 36V golf cart charger had a manual dial, I believe if I ran it twice it would desulfate (of course it would be boiling the acid out, too). But the one you linked to looks like it would do the job, the price is high, but not totally unreasonable, IMHO.

Pricey yeah. But not too bad to extend the life of a bank of 6 batteries costing $600.

I may even go into the desulphating business!

Should this keep my batteries from sulfating? Just bought two Costco 6v "golf cart" batteries at $74.50 apiece. Sears sells a Diehard 6v charger at 4 amps with a float mode for less than $20. Bought two and keep coach batteries warm and charged over the winter. Hoping to get more than the 4 years on the Interstate batteries that came with the Allegro.

The short answer to your original question is YES.. Here are a few facts and suggestions and one error in your post

"A standard charger ...13.x volts" That would be a single stage charger such as the magnetek 6300 and if you have one consider upgrading to a 3-stage unit like the Progressive Dynamics 9200 series (Or one of the many others which are just as good)

However,,, if the Magnetek is all you got.. Then over-winter pull the batteries (or just pull the negative lead off the most negative battery) and With the batteries still in series, JUST AS THOUGH THEY WERE IN THE RV, Hook up a Battery Minder PLUS or Battery Tender PLUS with desulfate,, Let 'em sit till spring.

Many good top end multi stage converters include either equalize, desulfate or both.

Just remember to keep the two batteries in series, as they are now, and always think of the pair, thus connected, as a single 12 volt battery.
