I just read another thread about his low battery beeping noise . I had this noise coming out of the what I thought was the smoke/ co2 alarm on ceiling. I was having house battery problems at the time - so does anyone know if that was supposed to work that way ? it did quit when we would get on the road ?
Depends on where it is coming from...but yes, a CO2 detector will beep with low battery. Once you started driving, it probably started charging from the alternator and it was good.
