Storage with no shore power

[RandyQ]

I am storing my Intrigue at a storage yard that does not offer shore power.
My question is how often & how long should I set my generator to exercise so to keep my batteries charge.
I currently have it set 3x’s per week for 100 minutes per run. I’m thinking that this might be in excess of what is needed.
I also have the auto charger start volts set at 12.1
Any help / suggestions would be appreciated!!

If the batteries are fully charged and there isn't any draw on them they should be fine when you de-winterize. They won't freeze. I would lift the negative battery cable to make sure there isn't any draw then don't worry about them.

Like Pete said
Looks like you are in California with warm winters, I would turn off all switches then remove the N post on all batteries and call it good. Then when you get ready to go start up the gen set let it run for an hour under load then hit the road.

Until I read your post, I didn't realize that there were RV generators that you could set to run on schedule. Nonetheless, I don't think it's a good idea to do this unattended in a storage yard and I would think that the storage yard owner wouldn't be happy with you doing so. There's too much risk of a fire if something goes awry and it's not just your rig that would be at risk. It's certainly not something I would do.

Here's a link with some good info on exercising your generator:

Your MH needs exercising as well so you might want to drive around at least part of the time your generator is running since idling isn't enough for your MH.

Rather than disconnecting your batteries, I'd install a simple battery disconnect switch. I'm not familiar with your rig but you may already have a switch for your house batteries.

I do have chassis & house disconnect switches. So, if I simply disconnect the batteries via these switches there will be no drawn & all batteries will stay charged? Not planning on letting the rig sit for more than a month or so at any given time during the year.
Thank you for the resposes!!!!

I think you'll be just fine.

If your coach disconnect switches are wired like mine are wired you will still have a drain on your battery’s . I would turn them off then lift the negative battery terminals as suggested.

We use a single $100, 100W solar panel on the roof to keep the house battery charged in storage in the Central Valley.

I generally turn off the house batteries and leave the chassis battery switch on for 30 days or more with no significant battery discharge. (Four Costco Golf Cart II batteries and two 8D Batteries Plus chassis batteries).

I also added a battery shut off switch inside near the entry door so I can turn on the house battery from outside the rig to extend the entry steps.

Our rig does not have the AGS system so cannot advise on that topic.
