Parallax Converter
Hi - we have a new(er) RV with a Parallax converter - series 7300. Can I leave this plugged in (charging the battery) 24/7? In our trailer we had a WFCO converter and I replaced it with a Progress...

Mex just posted this in another thread, but it belongs here too IMO.
"Or to put it in inverse fashion - the AGM will not like a straight 13.6 volt regime especially if the batteries are cycled. I pop my Lifeline every few weeks with 14.4 volts from a 13.3 float @ 26c. The battery amperage climbs to 21.2 amps then over a period of 11-minutes drops to less then 1.0 This tells me the battery is benefitting but I only do this after several weeks at 13.3 the system I have remains at 13.3 volts even with a 30+ ampere house draw....."
It seems to contradict the other advice that Phil likes. Phil does use his alternator every so often though, which must at least start of in the 14s? So maybe he is doing what Mex says and that is why his AGMs do ok.
I don't have a clue so I am just going to do what my AGM battery spec says. 14.8 for charging, 13.7 Float with the 7445, and if on a long term Float, then a shot of 14.8 or even 15.x once in a while like Mex says, and also what Mr Wizard does with his AGMs
