They are essentially specialized battery chargers, usually they are only capable of low amperage though some of them can run the full cycle between a charge and a maintenance trickle. They maintain batteries in storage without overcharging them.

Fancier ones are designed to round-robin through more than one battery so you can maintain multiple batteries in storage with one device without having an interaction if one of the batteries is different size or age or has a dead cell. BatteryTender and Noco Genius are common brands.

Wondering if you [OP] found an adaptor which worked with your outlet cover?

Thanks,

Does this apply to all circumstances or just when unoccupied?

If the former, what should full-timers or long term snowbirds that sit plugged in at the same spot for months at a time do regarding their internal converter?

An actual battery disconnect would work with relatively modern converters (say 90s and newer)... the converter would continue to supply the 12v bus but the batteries wouldn't be exposed to the converter output. The buzzy old boat anchors needed a battery in the system to smooth out the output.

With a really modern (3-stage) converter when you're actually using the trailer often or always, this isn't a big concern because it's easy to check battery levels and smell or hear if something's amiss.

I changed out the factory installed converter to an three staged battery charger. I have an 30 amp to 15 amp adapter that plugs into the trailer then I have just a heavy duty cord that plugs into the storage electric. Yes I leave my trailer plugged in 100% of the time it’s in storage. I check on battery water about ever two months if we don’t use it. My AS is an 2009 that AS installed a one stage battery charger (bad) What year is your AS and do you know what type of converter you have???

Hi

If you are in the trailer "doing stuff" then the battery is seeing a normal use cycle. It's not sitting there simply getting blasted at full charge by a gizmo that wants to charge it a bit more ....mIndeed, you still see some impact.

In a "stationary" 24/7/365 sort of setup you probably want to get rid of the battery entirely. You no longer need it for the break away function. You also would go with a very different 12V source.
