When I was getting the Walk About from the service tech when we bought ours, he pointed out the battery disconnect. I didn't know there was such a thing. It's not a topic of conversation around the fire.
"Hey, you got a battery disconnect?"
"No, do I need one?"
"I don't have one either."
"I got one."
"What's a battery disconnect?"
The conversation with the tech and me went something like this.
"...and here's your Battery Disconnect."
"What's a Battery Disconnect?" (see above conversation)
"When you store this unit for a period of time, pull (push, I forget) the disconnect so your battery doesn't get drained by things you might leave on or by the radio and things." ( a lot of radios have a clock display that's always on)
"I always leave our units plugged in when not in use."
"Then never mind."
Sooo, in answer to your question, it stands to reason to me that if I were to disconnect the battery from the rest of the electricals in the trailer to protect the battery, then disconnecting the battery will also prevent it from being charged. It'd be like removing one of the wires (preferably positive) from the battery itself.
I could be wrong though given the fact that I'm married.
