re: "Bryan:thank you for the battery maintainence lecture 101." I am very sad that you perceived my posting as suggesting you needed a refresher on a topic in which you feel you are an expert.

There are others that read these threads besides you and I.

Battery maintenance and storage is an issue that causes many RVers problems with their batteries.

Taking offense where none is intended is an issue that causes many threads to have problems.

I try to keep in mind the lurkers and others who may wander through the thread looking for solutions to their battery problems. I also try to avoid personalizing discussions.

I apologize for my comments. I do not consider myself to be an expert, far from it, but what I described is not knowledge that I think only an expert would have.
You "kind of" personalized it when you kept referring to my leaving the AS hooked up to shore power which I had explained in a couple of posts that I did not have.
I realize that a lot of people read these posts and this is not a two way conversation.
Time to move on, that was not the original intent of the thread anyway.
I obviously spend a lot of time on this forum as I have a LOT to learn from more experienced folks. Keep on giving your advice.

Being in the battery sales biz for many years, getting the most out of your batteries, comes down to one basic condition:

Lead-acid (including AGM & GEL's) need to be maintained at a full charge to get the maximum service life...

If you store your batteries, and can't maintain a full charge, you will shorten their life - pure & simple...If this is your pattern of use, you'll just have to replace em' more often!

I always use the example that one's daily driver's battery is always maintained at a full charge by the engine's alternator, hence most batteries in these types of installations last for many years, lets 4-6 years as a rule of thumb...

Your RV's battery should last this long or more, but you'll have to find a way to keep it 'float' charged when not in use, or remove it and maintain the charge periodically on a shelf in your garage, etc...

All batteries of this type will self-discharge as they sit in storage without any float charge - at different rates, depending on construction, temp., etc...Batteries left hooked to the RV's 12 volt system during storage will self-discharge much faster due to minute external loads; circuit boards in accessories, propane alarms, etc...

Also, a battery with a dirty top, will provide a path that can allow a small amount of current to flow between the terminals when moisture is present, as during winter storage months - Brush em' off with some fresh water & dish soap if your batteries are subject to road dust, etc...

One other issue I'm asked about, is about discharging your lead-battery completely before discharging to eliminate any 'memory'???...That's for for other types of storage batteries; tool batteries, video cam batteries, etc, NOT FOR LEAD-ACID BATTERIES!...

The grids inside a L-A battery expand and contract during charge and discharge - the 'deeper' you discharge the battery, the shorter will be it's ultimate life...worse yet, as the grid material erodes during this action, you run the risk of cell failure, in the form of two plates touching...hence that dreaded 'Bad Cell' diagnosis...

Some more Battery, 102...

Have you considered a solar charger or would this be a security problem at the storage area?

How about charging the Airstream (batteries installed) once a month with a small generator (if you have one)?

On the other hand it may be easier to just take them out, then store and charge them in the heated garage.
