The beep continued, every so often....not all that often...for a couple of days.

Hubby finally put a new battery in this morning. We almost immediately got the beep. Battery was fine and connected properly. We don't have the manual, so I looked on line and the only thing helpful stated that if the silence button got pushed, it might cause the beep once per minute, for up to 15 minutes, while the system reset itself.

That was about 10:00 this morning, and only the one beep (not once per minute) until just now. About 5 minutes ago it beeped and again right this minute. It's like it has a mind of it's own.

Does anyone know what we need to do? Thanks so much!!

You probably have a defective CO2 alarm. Call the 800 number on the detector and they will send you a new one, free.
