The number of people on virtual meetings with smoke detectors crying out for a new battery drives me insane. 9v batteries are not expensive and smoke detectors save lives.

Valmond@lemmy.world 1 day agoIt usually beeps like that because the battety is dying… Just change the battery!

It may be beeping because it’s past its 10 year working period. Some are programmed to beep continuously after 10 years to signal replacement needed.

Yep! Discovered our rentals smoke alarms were like 15 years old. Got us new ones at least.

Even if they’re permanently wired in with a Li-ion backup battery. I get why they do it, but realistically they’re probably good for longer?

It’s the sensors accuracy that is of concern at the 10 year mark, not the battery life

Ah. Didn’t think of that. Makes sense due to how they detect.

Most of the ones that exhibit that behavior are the types that relay on radioactive decay. decay being the key word there. They get less radioactive over time and need to be replaced.

“I’m sorry, sir, your smoke detectors aren’t nearly radioactive enough to be considered safe.”

Ah, I forgot they rely on decay. Makes sense why 10 years is the lifetime. They use Am if I recall?

TIL.

I thought the same thing but then remembered I had to replace mine recently and remember seeing smoke alarms coming with ‘lifetime’ liON batteries. They where even cheaper than the 9v ones. This is going to be more of a problem in 10/years. I bought the 9v ones because I didn’t want to deal with what happens when it starts dyeing.
