Charging House Batteries with Disconnect Switch Activated

I'm a new GT 351DS owner; first RV so I have what is probably a dumb question that I cannot find an answer to in the FR books I have.

My house batteries are 3/4 full and I'm getting ready to cool the fridge for a couple of days (using propane) before we head out friday afternoon.

Can I leave the battery disconnect switch activated and still charge the batteries using an extension cord and adapter?

If you mean that you are plugging into shore power (home 15amp receptacle using adapters) then your converter will charge your batteries if the battery disconnect switch is not set to disconnect. No need for a separate charger.

It depends. Where is your battery disconnect switch located?

Thanks Bubbles. Will it charge when the battery switch is set to disconnect?

The disconnect switch is in the stairwell on the left.

Just as a side note, I would prechill your fridge using shore power while you have it rather than propane. It's much more economical and you'll probably want every pound of propane you can get while on the road.

Typically, no. I don't know of a coach that charges the battery if disconnect is selected. Might be one but your's is probably not the one. Additionally; your chassis battery will also be charging. when connected to shore power. And yes, why not just use the shore power input for the fridge and save the propane for the road.

I think you're right. I'm going to leave the switch to connected and charge it.

Yarome: Are you saying that I can run the fridge off my household power or do I need 30 amp or 50 amp for it to run. If I can do it using my regular power than I would absolutely prefer to do so. I just didn't think it was an option.

Correct me if I'm wrong, but you should be good. That's just a soft disconnect switch that cuts the power to your "house" bus. Your battery/ies will still be charging.

Yes you can. It doesn't have to be a 30 amp shore power. Your household 15 amp is quite sufficient.
