Trailer Battery Load Support
As a followup to my recent discussion about my newly acquired CTEK Multi US 7002 Charger I'd be interested in some further input on the subject of trailer battery load support. :) First, I should c...

Still not clear on types of AGMs for what work. If you are usually on shore power but once in a while do a deep cycle is that the same as what a UPS does, so use a UPS type AGM? Or do you still need a "real" deep cycle battery (that doesn't like being floated) ?
Then you get these "telco" AGMs but are they all UPS type? Acid starved vs not acid starved? Is the not acid starved in danger of venting gas inside your rig same as a Flooded?
Or is there more than one type of "telco" and some are good for Rv deep cycle work and others not?
Then Mex or somebody said AGMs should not have high draws just low draws, but then we have (some?) AGMs being real good at handling high draws with less voltage sag. Do you pay a price for that smaller voltage sag by killing the AGM "before its time?"
BTW I can stick my truck camper batteries outside in the truck bed ahead of the wheel wells before sliding the camper in, so I don't really have to have the battery bank inside making fumes, but it is a bother. If all this AGM business gets too complicated I will do that :)
