Rated 1 out of 5 by from Battery Expired after 3 months in smoke Detector Included with my "First Alert" smoke detector 2 pack were new, Duracell Ultra CR2 batteries sealed separate from the detectors. Expiration date on the batteries are March 2021. I installed the smoke detectors after inserting the batteries 3 months ago. One of my detectors started to chirp last night indicating a "Low Charge Battery". ??? Being a Safety Device for the home, seems like it should have lasted a few years being it is included in a detector designed by a well known brand. Being a special size they have us over a barrel, charging a high price and poor performance.
