I just got off the phone with the tech department at Parallax. He explained to me in great easy to understand detail what to do in my present situation.
I plan on upgrading my charger/converter to one that has temperature control that monitors the battery temperature and adjusts the charge accordingly.
It also features a boost mode if the battery requires it. I will then purchase 2 AGM batteries and be done with it.
Parallax currently offers a couple series of two-stage temperature compensated converters - their 4400 series and their 5400 series. Both series are "right on" with respect to specs and I would pick a unit from among these two series if I were to ever replace my RV's stock 7345 Parallax converter, as follows:
The Parallax 4400 series has available optional "TempAssure" temperature compensation of their output voltage in both charging stages. The higher voltage temperature compensated boost stage runs for 4 hours every time input power is applied to the converter, before dropping to a lower voltage temperature compensated float stage.
Their 5400 seried also has available optional "TempAssure" temperature compensation of their output voltage in both charging stages. The higher voltage temperature compensated boost stage runs for 4 hours every time input power is applied to the converter, before dropping to a lower voltage temperature compensated float stage.
HOWEVER, the 5400 series also adds power factor correction to it's input circuitry ... an outstanding feature that is absent in a lot of RV battery chargers ... and can be very important whenever using a generator for input power to the converter when drycamping.
Here's a couple of links that need to be checked out thoroughly to see just how much Parallax is offering in these two series ... either one of which appears to contain models that would be a perfect match for most, if not all, AGM batteries:
