plugging into the on-board charger

[Michael Patricia Doucet]

We have a 2013 550 Tear Drop. When plugging into the on-board charger after about 15-20 hours the CO2 alarm in the camp inn goes off. Does this indicate a problem with the on-board charger? With that being said if we went to a campground with shore power, how do I prevent the CO2 from building up that would set off the CO 2 alarm?

Crack a window and the roof vent open a little.

CO or CO2? There is a big difference.

I would also ask how old your detector is --- these typically have a 5 year shelf-life, then they need to be replaced. That aside, I have some questions. Does the detector have a propane sensor as well? Any "thane" gas will set those off -- including methane -- ask me about Joe the pug some time (name changed to protect the guilty)

Normally a battery shouldn't offgas any CO/CO2/*thane gasses. What formula battery are you charging? What is its state of charge and how old is it? Is there a chance it is 'old' and possibly over charging?

Is the camper in a garage or outside when this happens?

Is this a one time or is it a repeatable event?

Sorry, It’s a CO monitor

Well I thought you may have been inside with all the windows closed for too long, but that's different. As said by others a battery charging shouldn't be emitting CO. What type of battery do you have? If it's an open flooded cell battery it would give off some hydrogen, but if it's an AGM sealed battery it shouldn't, so not sure what your CO monitor is reading.
You mention that it happens after 15+ hours of charging, and then go on to ask if you were in a campground with shore power how would you keep the CO from building up. That indicates to me that your current experience is not at a campground. Are you experiencing this while charging in a garage? Is there a water heater in there too, like we have in our AZ garage? or some other source of CO, like cars coming and going with their engines running for a little while in the garage?
Just trying to figure out CO sources other than a battery charging.

I have a CO2 detector in my safe room. I also have CO2 absorbers and o2 to keep the atmosphere balanced. If you get a “stuffy” feeling in the CI then you need to ventilate a little. I have had my CO detector sound off on its own while sleeping, no appliances running inside or out so I only use it when using the propane heater.

I believe Cary mentioned an issue with this, only when using shore power and he tried several different detectors..I may have gotten lucky with mine , no issues so far, I wired it into the cabin usb port wire
