Have a 2012 with the original 7355 converter and size 24 Interstate batteries. I leave the unit plugged in and "in use" (do not place the switch in Store mode) all the time. Batteries going strong and have only added a bit of distilled water to each battery on two occasions. For the lead acid batteries, I can't see how I could do any better.

Does anyone know if the PD4655 Converter will charge AGM batteries? I just replaced the factory unit and the PD doesn't seem to change from the normal mode. Output is 13.8 V at the converter output and batteries. It has run for over 24 hours with no charge state change.

It certainly will charge AGMs and I'm on my 11th year with a pair of group 27 Lifelines and a PD converter in a Lance TC. The normal mode is 13.6 give or take a 10th or so and the boost mode target is 14.4 VDC. It will not boost necessarily unless it determines your batteries are ready for a 4 hour boost. Usually after a drive to a new location and plugging back into shore power you will see boost but not always. You can always over ride and hit the boost button. Just make sure you have a way to know when you are fully charged and not let it sit there too long for the sake of it. Best to leave it in the automatic mode but there are times when over riding makes sense. Hopefully you have the remote so you can monitor it from the outside of the panel when you walk into your Airstream.

Hijacking the thread for a similar question. We have a 2010 20ft FC, and the stock 7355 converter just crapped out. We could get a newer replacement model 8355 (a bit deeper dimensions in the lower converter section) on Amazon for $445CND. Or I could purchase a 55RU (upgraded) stock replacement lower for $370CND.

Anyone able to give the pros and cons of each? Considerations include living and playing north of 51 latitude, use both AGM and flooded cells as the need and conditions dictate, & stock solar charger and controller installed.
Thanks!

I would say no to the upgrade. In my situation, there wouldn't be any value for the money spent.

For incrementally more money than an upgraded converter, I was able to install solar, which has its own 4-stage charge controller with temperature compensation. I park outside. So it alone is what manages the day to day charging and maintenance of the batts.

Therefore the original converter is only utilized when I go camping in a full hookup sites. In these situations, I use the trailer in the store position, which decouples the converter from the batts.

So the original converter-charger is largely used for its converter function and rarely as a battery charger anymore. Perhaps the only use case as a charger would now be boon docking in extended overcast conditions where I may use it with a generator.

Thanks! I've ordered the OEM replacement 55RU. I am happy with the solar package, but there are a lot of additional draws on the 12V, especially the fans, not to mention the various tank heat pads, that for several months of the year the converter will be needed with either shore power or the generator hooked up.

Before you "hijacked" these folks were helping the OP with better options you could have even got in Canada locally maybe. You are not going to like that 55RU unless you don't run a battery or voltage doesn't matter. It will charge your battery single stage though if that is what you need.
