Even if they’re permanently wired in with a Li-ion backup battery. I get why they do it, but realistically they’re probably good for longer?

It’s the sensors accuracy that is of concern at the 10 year mark, not the battery life

  Ah. Didn’t think of that. Makes sense due to how they detect.

Most of the ones that exhibit that behavior are the types that relay on radioactive decay. decay being the key word there. They get less radioactive over time and need to be replaced.

  “I’m sorry, sir, your smoke detectors aren’t nearly radioactive enough to be considered safe.”

  Ah, I forgot they rely on decay. Makes sense why 10 years is the lifetime. They use Am if I recall?
