First Alert smoke detector...non replacable battery supposed to last 10 years...dies after 2...for warranty contact, the verify you're human puzzle does not work on 3 different browsers I tried
I just used the phone number on the back of the device to call them. I found them rather pleasant to deal with and they sent me a free replacement within a couple of days. Good luck, friend.
If you really want to pursue being ripped off I would recommend contacting your local district attorney. They seriously do great work for us common folk.
