The First Alert Onelink Safe and Sound has a very bad flaw that will drive many people who buy of eBay crazy. The backup battery is a NON REPLACEABLE battery and brand new, never opened boxes are chirping after install. I bought 2 units from 2 different vendors on eBay that were brand new still in plastic seal. I install units and immediately found out that battery on both units were 1 bar ( very low). That both chirp every 30 seconds. You can not replace these batteries. What’s bad is unit was manufactured in 2018 (now 3/20) and batteries are supposed to be 10 year lithium batteries. I spent $125 each & now I have same problem as units I replaced, chirping! At least I have Alexa, but a true waste of money. I will never buy another First Alert product again. Mind you, I cannot blame sellers for this problem. First Alert should have used regular batteries like all their other smoke/co detectors, even if we have to change batteries every 2 years. I also bought Nest Protect smoke/co detector and it works great. Only thing wrong is that you only have 7 years and unit will stop working. But no chirping. You are now warned. Read full review
