Battery maintenance in storage w/o shore power?
Under the previous topic When To Replace AGM Batteries - Recalibrating Battery Monitors, Paul B. noted that batteries should receive shore power when stored. 

My LD is stored for months at a time in a large indoor facility without access to shore power (a not uncommon circumstance) one hour away from home.  I had a quick disconnect switch installed to ensure zero "phantom" drainage during storage.

Given these constraints, what else can one do to provide "the love" that Paul B. advocates for batteries?  I assume they should be fully charged when stored, but what else could one do indoors without shore power? 

We use our LD 2-3 times per year for trips 2-6 weeks.

Beyond fully charging and then disconnecting the battery, is the only thing you could do is try running it occasionally, in the winter.
The good news is that AGMs have a low self-discharge rate, so you are probably OK with what you are doing.

What Larry wrote. Could also consider off loading the batteries to take home and keep them on a charger. But that may be a bit of an extreme.

Charge a healthy battery to full, lift the ground connection, and you will find everything OK after storage. This applies to house and chassis, both.

I have also taken house batteries out and kept them at home. This works best if they are sealed batteries (no leaks) and if the person moving them is strong. In my case, "yes" and "not any more!"

I have removed batteries and taken them home from cars stored for months.  It's a good idea.

Not an option with the Trojan Reliant 903 replacements I plan to purchase.  They weigh 114 lbs.....each.
