Yes, but no. You really should replace your detectors every decade. They will likely work perfectly for twice that, but is it worth the risk over like $100 in smoke detectors?

So it does sort of force you to replace it after a decade, but you should anyhow.

It’s also well worth it, because getting on a chair or ladder and buying new overpriced 9v batteries every year (if you’re all proper about changing them) is a pain in the ass compared to once a decade. The more of a pain it is to get to your detectors, the more a 10 year one becomes worth it.

You’re supposed to hit your test button once a month to check their functions, but I dont think anyone anywhere actually does that. If they tell me they do I’ll just assume they’re a liar.
