Battery or 10yr smoke/CO2 alarms?
currently needing to upgrade a new property of mine and am stuck trying to figure out which would be my best option to go with: Combination CO2 & Smoke alarms that are 10yr sealed or just plain jane battery operated. I've been seeing a lot of negative reviews and comments around sealed units going off WAY before they are supposed to or just giving false alarms in general.
Please let me know your opinion or if you have any experience and prefer one over the other!
