Not XKCD - Smoke detector batteries
(lemmy.world)
A community for a webcomic of romance, sarcasm, math, and language.
Pro tip... If your detector is beeping at 2 AM and you don't have/can't find a replacement to make it stop... your freezer is sound proof. :)
Instructions unclear, stuck in freezer
remove the battery?
Doesn't work with all detectors. The beep has it's own buried battery because the main one died.
