I have no idea what converter was in my previous fifth wheel, but the batteries were going on 11 years old, and other then when on the road it was plugged in. I was under the impression most converters if not all do not overcharge batteries these days. Never had a problem, this present fifth wheel has been plugged in for 7 months ,and the batteries are fine . As you said , I check the water a couple time a year.
IMO its just the opposite of some of the thinking here , keeping my fifth wheel plugged in 24/7 has contributed to the health ,and longevity I have had with my RV batteries .
they are getting better, now its more or less the reliability of the brand, I have ownd a few trailers with WFO converters and never will again. they fail and destroy batteries.
rv companies done spend extra money to make sure your batteries last longer or to make sure your converter will function properly longer than the warenty. the less money they spend the better for there bottom line.
there were still single stage chargers being used in the lait 90's and early 2000's then two stage chargers became all the rage and now we are seeing 3 stage chargers regularly, but dont think they are quality units or that they put out the ideal charge voltages for your batteries. I usaly take them out and put in an intellipower with the charge wizzard, for solar I will only use a unit that will let me customize the charge voltages for different stages. playing with a Renogy mppt controler right now, im pretty impressed so far and it is much more afordable than the standards,
