I was about to buy one when I saw this: “Kidde P3010CU is a 10-year, sealed battery”.
Nope, I hate these 10 year sealed non-replaceable batteries. You would be lucky to get 3-4 years out of it, at least based on all the ones I have bought. Then you have trash. In California the smoke detectors have to be non-replaceable batteries, but you can still buy the combo units that take AA batteries, and that is what I buy now.
