My 1st one started beeping at 5 yrs. And my 2nd one started beeping after another 5 yrs and I replaced it 2 weeks ago. Almost like a built in timer.
That is my suspicion. If I can remember, I'm going to disconnect mine over the winter hibernation and see if I can get more than 5 years out of it.
I also suspect a few extra years can be had if disconnected from the battery each winter. I bought a 7 year old TT last year and the detector was one of the first things I checked. Sure enough, it was original and expired but was not beeping or alarming so I suspect it was disconnected every winter.
I replaced my propane only detector with a CO/propane unit and dated the face with a felt tip pen.
