If a dealer disconnects the chassis battery, the engine won’t start. What was the dealer going to do with it at that point?
Just find it, and pull the negative lead off the battery - once it’s situated where it’ll be sitting for the winter. But do put a battery maintainer on it, and plug it in every once in a while for a few days. Or just leave it plugged in.
I plug a maintainer into the one 12V power port that’s always on, but I only plug in the maintainer once a month for a few days. In cold weather, FLA batteries don’t self-discharge very fast at all. My van has a battery chassis battery disconnect under the gas pedal, which I can reach just by opening the driver’s door, so I leave it disconnected until I want to run the maintainer, then I disconnect it again. The parasitic chassis loads will pull the battery down in a few weeks or so if I don’t.
