Battery powered!!
After having a lithium battery fail and start smoldering in a 3 year old "10 year lifetime battery" detector, I purposely shopped for one the takes good old batteries.

Reliable and Easy-to-Use Battery-Powered Smoke Detector
The Kidde Smoke Detector with AA battery power is a great choice for simple and effective smoke detection. It’s easy to install and the battery-powered design ensures that it will work even during power outages. I appreciate the LED warning light indicators that let me know the status of the detector, providing extra reassurance. The alarm is loud enough to be heard throughout the house, offering reliable protection. The battery lasts a long time, and the unit is compact, so it doesn’t take up much space on the ceiling. Overall, this smoke detector provides peace of mind with its reliable performance and user-friendly features.

Many false alarms in first month
The media could not be loaded. Purchased 2 KIDDE alarms, model 20SDR. Installed 1/30/25, followed placement instructions, one in hallway outside master bedroom, one at top of stairwell. Getting repeat alarms. Kitchen is 30 feet away but had to start closing kitchen door for any heated meal (never had to do that with other alarms). The real problem is I can't shut them off! The hush button rarely works as user guide instructs. This afternoon (3pm, 3/6/25) both alarms went off within minutes of each other, though no fire and kitchen door closed. I physically moved one alarm near open window and put another under a blanket. They eventually stopped but red light stays on (no green light). I'm stumped. Need to try another brand.
