Electrical ghost

[Gandy Dancer]

I have a 2016 370BR
It has been put away for the winter sadly.
Recently I went in it just to see how Monty was doing over the winter.
Please understand that he is winterized, master disconnect off, battery removed and inside on a charger.
I think I heard the CO2 detector beep a couple times.
Is it possible there is residual power still in the camper.
Never in 30 years of campers have I pulled a battery and had this happen.
Am I missing something on this new camper?
Help!

Sure it wasn't a smoke alarm chirp

Agree it is most likely the smoke detector which is powered by a 9 volt internal battery. Remove the battery and it will stop chirping. Make a note to replace it in the spring.

It sure can if you have battery back-ups on your CO2 detectors:)

I agree, either smoke or CO detectors since they are self powered and cold will make internal batteries fail. JM2¢, Hank

No Ghosts, I would check all battery operated Devices/detectors and as stated good time to replace batteries for the upcoming camping season. Yeap, still cold up here
