As an aside, I genuinely have no idea what the fuss is about. In my entire life, I have never been bothered by a low battery smoke detector alert. I take 5 minutes and change the batteries in my detectors twice a year and they never ever beep.
This requires being very organized. If you are that organized, hats off to you. Many people (myself included, I admit) aren't.
Of if you live in a majority of the US, when you change the clocks, change the batteries.
Neither of these schedules will sneak up on you. If you don't change them and it wakes you, it's your own fault.
Sorry to sound snarky, but it's not _that_ complicated.
Your experience is not mine, and mine is not yours. Why is it so offensive that someone has tried to make my life better? Is it just jealousy that they didn't work on one of your problems?
However if you insist on focusing one a singular viewpoint then I will remove myself from the conversation.
I just checked, apparently my stove has a clock, too. It's not set to anything resembling the current time.
Neither of these appliances are things I would ever look at when I want to know what time it is, so I just file them under things that are not clocks.
