My smoke and CO alarms don’t depend on the clocks, so mine should be fine

Your batteries don't last forever (even electric ones have backups) and it doesn't hurt to check how old they are, and if they are still working.

The ones that I have are generally good for ten years. When the batteries start to go, they emit an extremely annoying piercing alarm. The fire department has had to break into several homes in our neighborhood for this problem which just turns out to be that the smoke/CO detector needs to be replaced.
