Is "Plugged In 24/7" the same as "Juiced Up 24/7"? Still have our Original WFCO and No Boiling! Youroo!!
Youroo, you can't make a blanket statement like that, I don't know how your unit is wired. Hell I don't know how you are wired. Everyone with common sense, can see the benefits of a 4 stage charger to a 3 stage. Not all WFCO's are bad, and I also do not have sealed or maintenance free batteries... PS: read post #4 when the OP answered Turbs Question.
Last year had a friend complaining of his batteries being constantly 'boiled' while charging. He replaced his converter, then his batteries, and checked his wiring. No difference, still always water on the tops of the batteries which he thought was caused by boiling. So he would add more water. Turns out he was over filling the batteries with distilled water. Once he learned the proper level for batteries, no more problem. Now his wife won't let him read the forums

Yes, one of the fuses is the charger in the converter. Pull the fuse, no charge. You can replace the charger portion of the converter from amazon with a better unit.
Replaced my WFCO on my last camper with a PD after it cratered. Will do the same with my new camper when the time comes. I believe it is a breaker that disables the converter portion. Should be labeled.
My A-frame had a similar problem with the batteries losing water. Started checking voltages, and found the WFCO converter never went into trickle mode (13.1-13.2V). The WFCO specs say that after 44 hours of being plugged in and a steady, low current load, their converter will drop from normal mode (13.7V) to trickle mode. My WFCO did not meet its own specs. Not unusual for WFCOs, but there are obviously millions of WFCOs that do meet spec (or their owners don't know).
I replaced the WFCO with a "drop in" Progressive Dynamics replacement. Works really well, and goes into all 3 modes readily. My batteries are happy.
I did install a battery cut-off switch on the battery box so I can easily disconnect the batteries. And last fall I put in a voltmeter with a switch to check on how batteries or converter are doing. When camper has shore power, voltmeter reads converter output. When dry camping, voltmeter reads battery voltage.

That being said there are literally millions of them in use by RV owners who never think twice about it, do not know what a converter is, does nor care, have never had a problem with one, and never have joined nor even visited an RV or camping forum. Ignorance is bliss I guess.
Yup which is why one of my neighbors bought new a new battery for his camper every year.
I have had a variety of converter/chargers over the years, the absolute worst was the Uni-volt in my Airstream, quickly followed by the 4 out of 5 WFCO that either didn't work properly or crapped out completely in the first year or so. Dealing with WFCO on getting a warranty repair is not pleasant, cheaper to just go ahead and upgrade to the PD unit rather than play WFCO's games.
