Battery switches by door to use or not .

Put a voltmeter across each bank of batteries when plugged in to shoreline and then cycle them on and off. You don't want one of the switches turning off the charging circuit path. Not likely but worth checking. Turn them off otherwise.

IF.....you have AGM batteries OR a good charger/converter that really "floats" the batteries....there is NO REASON to do anything to the batteries while plugged in; including turning any disconnect switches off.

Those switches are to be used during storage when/if it can't be plugged in.

Thanks YC 1 , should I leave the RV plugged in with both switches off ? or does it matter ?
Thank you

On our 96 Southwind I leave both switches on when connected to shore power. Never had any problems.
However, I keep it at home so it is checked often.

Plugging in at home isn't real convenient for me so I turn off the motor home coach batteries to prevent discharge. Then once a month or so I do plug in to make sure I'm charged, especially in winter. No problems.

Checking the voltage on the batteries before and after you plug in and then turning the switches on and off to verify they do not effect the charging system you can leave them off or on when plugged in. But if one effects the charging path you definitely want to leave that on when plugged in.

If you have power and a decent converter (3 stage or better) leave 'em on

If you do not have power or a Magnetek 6300 Shut off.

The only time I use mine is when I get propane.. Like this morning.

Thanks for the help everyone , I now have a better understanding .

A 2013? You would think they would have a decent multi-stage inverter or converter/charger but then you never know.

As others have noted, if you have good multi-stage charger, like one from Progressive Dynamics, Iota, Magnum or Xantrex, that has a float or maintenance mode there should be no problem in leaving the battery disconnect in the "On" position.

On the other hand, if you have one of the "battery boilers" as I call them, you'd want to cycle the switch off and only turn it on when needed to keep the batteries charged. On my old rig, and before installing a Progressive Dynamics unit in my newer one, I used to turn the disconnect to off and use a Deltran Battery Tender Plus to maintain the batteries.
