Electrical Question

[lmpres]

On my last trip this year, when I got to the campground, I noticed my C02 alarm chirping. I had already plugged in to shore power when I noticed it. Thought nothing of it.
I got home, plugged in, and same thing. Again, wasn't sure why that was happening.
Went out yesterday to move the trailer for winter storage. Hooked up to my truck, plugged into my truck, and no power in unit to raise the landing gear. I re-plugged into shore power and landing gear raised with no problem. (also, noticed c02 alarm chirping again.)
Could this be because of a dead battery? Was thinking last night and it is the original battery that came with the unit.
Any help is appreciated!

Get out your voltmeter and post the battery voltage.

Yeah, the units do go bad and I'd immediately replace one that acted squirrely. I've had one go bad and so has another family member. They're inexpensive.

"Chirping" generally means it has a system issue.. Possible issues are:
Low battery
Checksum error or other system error
More than 5 years old time out.

For the price of a 9v battery, replace it, if it stops chirping, you're all set, if not replace the alarm unit, they have an age limit, but right now i don't remember exactly what it is, 5 maybe 8 years, look on the back of it, it should have a sticker, suggesting when to replace it.

It has timed out, replace.

Your converter is working (you have 12v on shore power) but your house battery is low (no 12v without shore power) but the alarm still chirps even though you have 12v on shore power.

Your alarm might be one with its own little batteries that are low.

Meanwhile your house battery is low even though the converter works. So the converter charging is not reaching the battery or else it just can't be recharged anymore.

Yes, certainly could be a dead battery. You don't say what year your trailer is so no way of knowing how old the original battery is. But signs point to that as the problem. Easy way to find out is to check it with a multi-meter. Anything else and you're just guessing.

All I know is that most all alarms will sound if low voltage is detected
