Replacing batteries in chirping smoke detectors at 2:30 am. 🪫😬

@canion Everytime. Replacing with 10 year rated lithium batteries. 🤓

My understanding is that the lithium battery charge does’t weaken, it just stops without warning. If so, you may not get the ‘low battery’ chirp at all, and wouldn’t know if the detector is working or not.

of course of course 230am… Well I guess a good time to start your Saturday 🫠

@rogerscrafford Worth noting for sure. In my case these are also wired into the house electric so battery is truly just for backup.

Now all you need is a ten-year calendar to remind yourself about the battery.
