Yes. Your propane alarm will run your battery down over time. Best thing you can do is take the battery and keep it on a battery tender. It will last much longer that way.
Either a battery shut-off or, for winter storage, I pull it. There's lots of "Ghost" draws off your battery, so if your storing it for more than a week or so, I'd either disconnect or remove it.

I pull mine, put it in the basement and connect it to a battery tender. My lawn tractor & larger tractor stay in an unheated shed with a battery tender and they startjust fine in the spring, so I guess you could just pull the cables, leaved it out side with a tender ( if you have elect near your storage) and you should be fine.
