Yes, the detectors inside age.
You must replace all with the same brand as different brands won't talk to each other over the third wire. (except if specifically noted).
Also, I think smoke detectors are considered toxic waste.

They have a tiny bit of radioactive isotope in them if it's an ionizing type. Iirc Ameeicium or something like that. Most just toss them in the trash as there is no outlet to "properly" dispose of them. The optical ones are just electronics nothing hazardous in them.
Also a good idea to replace every so often to reduce annoyance trips. They like to go off at 2 am for no reason.

The new ones have a lithium ion battery that is good for the ten year life of the detector. No more changing 9v batteries.

Bob, in my county, we have toxic round-up day once a month. Drive over to the dump and get in line. They take everything from you through the window or the open trunk and you never even get out of the car. Don't have to sort much either. They do it all.

When we looked into this a few years ago for our home, it ended up making more sense for us to just go with the battery only detectors. One alarm going off is easily heard anywhere in the home, so there wasn't much reason to wire them all together. Using the battery only versions cut costs and made it easier to replace them.
Verify this yourself, but I recall the dual sensor smoke detectors being best at detecting different types of fires.

Code requires wired plus battery backup plus wired together. I have them due to a remodel.

) but that was always the retro fit battery-only models. Do I need to replace these...I guess I can search the internet for some.
