I've had fairly good luck with Kidde brand from Home Depot. I have four of the smoke/CO2 detectors. They're about $45 each. The ones I have take three AA batteries that load from the back. They don't get wired into the house. I think the ones that are hardwired either get fried by lightning or power line anomalies. I have not seen a lot of people with them hooked up long-term, and I HAVE seen a lot disconnected.
They seem to be transitioning to permanent battery detectors that (supposedly) last 10 years. Yeah, I'll believe it when I see it. KEEP YOUR RECEIPT, and return them to HD if they fail. Some will be duds and fail within a month or two. Others will last probably three to five years. I think that's about as good as you're going to get around here. So keep your receipt and hold them to their warranties.
