Two years ago I installed 5 units of the new 10 year smoke detectors. Last night at 3AM I got the dreaded battery chirp from one of them (so much for a 10 year battery). Luckily when I installed them, I cut off the front of the box and kept it along with the receipt and the paper manual.
I called the 800 number (they are First Alert brand) and gave them all of the info and they are sending out a new one to replace it. I told the nice lady that I have 4 others and asked if they are all covered. She said they are all guaranteed for 10 years and if anything goes wrong during that time they will replace them for free.
My point--make sure if you buy 10 year smoke detectors that you keep all of the paperwork so you don't have to drop money to replace the ones that don't last 10 years--just call the customer service number. I have a feeling I will be calling multiple times...
