I have a plug-in CO detector. A few day ago, it started intermittent beeping about every 30 seconds or so. This usually indicates the battery needs to be replaced in a battery operated unit. Mine does have a 9-voly battery as back-up power. I removed it and tested it and it was okay. I plugged it in again and it started beeping intermittently again. I read the fine print on the unit and to my surprise, it said that after 5 years it will do this to alert the homeowner that the whole unit should be replaced. What a rip-off - I have to but a new detector every 5 years at $60 a pop? Does anyone else have an AC powered CO detector and have to do this?
