Actually I can't hit Costco.com without getting the same error, using Chrome. Went to my Brave Browser and I don't get that error but costco.com brings up a nice big whiteboard. Brave tells me "there's something wrong with this site." Evidently they'll report it to Costco's web slaves.

Last year I got all new smoke detectors from my house. It was not cheap. I basically got the recent version of the ones I had around the house. Like 5/10 of mine all would beep because the "expired" chirp was going off on them and I just unplugged them. They would still chirp even if I put a new battery in them and then I looked up the light code and it meant they were expired.

The date on them was like 8.5 years ago (before we moved in) so I figured that was close enough to 10yrs. So I just got 10 new ones and it was around like $300 from Amazon.

The best part about the new ones is that they take AA batteries. I always have tons of those around so it's easy to replace the batteries when need be.

I got these ones.

They had 6 and 3 packs at the time too for a discount, so I got a 6 pack, 3 pack, and single one to replace em all.

uh, you know in MD you're now required to install the 10 year, tamper-resistant, non-removeable lithium battery types, right?

That's going to be another expensive replacement!

I'm good.

For homes constructed PRIOR to July 1, 1975: Under the old law, for homes constructed prior to July 1, 1975, a smoke alarm was required outside each sleeping area. The smoke alarm could be battery- operated or hardwired. Under the new law, for smoke alarms that are battery-operated, the units need to be replaced/upgraded with new, sealed, long-life smoke alarms equipped with a hush feature.

Mine are all hardwired to the home electricity and the battery is just for backup purposes.

EDIT: OH, OK, ....I guess it still allows for hardwired alarms? That's weird....seems, less reliable/safe, especially if you have no idea that those batteries are now dead after x years just sitting around, haha.

They still beep when the batteries die. The ones I replaced are were older models of the same ones I got.

Yeah, my understanding when this law was enacted, was that no hardwired detectors were allowed. I guess there was a grandfather clause that allowed you to continue with the hardwired alarms if installed at a certain age, but I thought that any new replacement, of any type, would have to be the 10 yea non-tamper types, regardless of anything.

The grandfather clause only works if you have enough men to run the bucket brigade.

is an old never used smoke alarm still usable? - Google Suche

My impression is that your 10+ YO never used smoke detector is likely to work, but since it's to be entrusted with your life and that of everyone else in the house, it's not considered trust worthy. The components aren't thought to be "trustworthy" for that particular usage after ten years. It's like if you had an FM receiver NIB for 10 plus years. Would it work? Probably. But less likely than if manufactured 3 months ago. But you might want to use it anyway.

The new 10 year non-replaceable battery units have this philosophy built into the units.
