When are non-Daylight Saving Time areas reminded to replace smoke detector batteries?

Setting clocks and replacing smoke detector batteries have always gone together for as long as I can remember. But this past weekend I started wondering what areas that do not practice DST do to remind people to replace their batteries. Arizona? Hawaii? Are you out there?

In Hawaii, we wait for the detectors to start their low-battery beeping.

My mom also used to write the date she changed the battery on a little Post-It inside the detector.

Puerto Rico here, also when they start beeping like all get out in the middle of the night.

How do you remember to replace the batteries on other things? It stops working, starts beeping, or gives some other warning signal and you change them.

They beep. For rentals and public buildings they have to do it on a schedule. I just remember it as fall maintenance.

Did you change your carbon monoxide detector cartridge too?
