" ...  Supposedly it is to last "10 years" but mine lasted two. ... Maybe it was defective.  ...  "

" ...  The unit started chirping after two years.  ...  "
comment
" ...  Then we checked the manufacture date, and it was September 2018. ... We don't know if this detector was previously used, returned, defective, or something else.  ...  "

" ...  Malfunctioning right out of the box  ...  "
comment
" ...  It worked for exactly one year. ... After a year it started with the five rapid chirps that mean the unit has reached the end of its life and the only way to stop it is to permanently deactivate it, which is not reversible. ... There is no reason this should have stopped working. ... If the other two I have work for at least two or three more years I will conclude that this one was just a lemon and return to my original plan.  ...  "

comment
" ...  I opened the battery compartment and one of the batteries had that green corrosion acid type stuff on one of its terminals. ... I don't know if the detector or the battery is to blame. ... Addendum: My other one gave the low battery chirp just now, a couple months or so after the other one did. ... I replaced the batteries with new ones (verified they're good on a battery tester), but the alarm shows no sign of life.  ...  "

comment
" ...  I like everything about this product except that after three years it's begun its Low Battery Chirping when the batteries aren't even low. ... Second time in a week I've checked the batteries replacing them once. ... Battery voltage 1.496V (not dead by a mile).  ...  "
comment
" ...  Last week it started "chirping" to indicate low battery -- even though I had just replaced the batteries a month earlier.  ...  "
