I think this is why smoke detectors take 9-volt batteries now.
Haven’t they always taken 9v?
they have, although some do take AA or AAA batteries but its very uncommon. some especially carbon monixide dectectors have internal batteries that require replacement.
We just bought new smoke detectors and they take AA, I bought a 9v just out of assumption and got home and was blown away
9v are just two AAs wrapped together. So not surprised.
Eh not quite. AA are 1.5v so two would only be 3v.
You might be thinking of the big 6v lantern batteries. They’re usually 4 x 1.5v cells together.
I thought I watched some YouTube video where they linked them and it worked. But who knows how accurate the numbers were. I guess not since you know.
Unrelated but a few days ago I found out you’re not supposed to stick two 9v’s together when I burnt the shit outta my fingertips :3
Yeah… That’s basically creating a short circuit. Don’t do that.
Harbor Freight to the rescue!
I have AA batteries that are rechargeable, and I’m challenged to find a use for them
Once I had a kid, the demand for AAs skyrockted. I already had a bunch of nice Eneloop and generic equivalent rechargeables and a fancy third party smart charger. But when a kid gets a LOT of toys, the rechargeables turn out not to be a good solution. You need to have a large quantity of batteries that get rarely used, unless you want to be swapping batteries every time they switch toys. Good luck with that, lol.
And even worse, if you have a bunch of rechargeables in toys all over the house, they can start getting trashed or given away inside those toys!
So it was like an overflow error that put me back at the beginning of the battery user progression. Buying alkalines baby!
Everything I own that I’d like to use rechargeable batteries in, explicitly tells me not to use rechargeable batteries in it. It’s super annoying.
All the things I have that use batteries don’t seem to function well on rechargeable (such as my electric door locks). So I also have a bunch of them I don’t know what to do with and still have to buy disposable. 😔
Wow, that sucks. It has worked for me. I have a zwave lock that I have been running on rechargeables for about 6 years now. Even now with the abuse of a 5 year old kid who learned the pin and insists on locking and unlocking unnecessarily, I only charge the batteries once every 6 months! I thought maybe I was exaggerating, but I have a home assistant automation that alerts me when battery level is 50% or under, which is when I charge, and yeah, just about every 6 months. Maybe it’s because I spent too much on “good” rechargeables? Or not, it might be placebo
It could very well be that yours are “good” rechargeables! Mine are just Amazons brand lol. If I use them in my locks I have to change like every 4-5 weeks.
Oh wow. I suppose it could be the locks. But yeah, they’re good higher capacity rechargeables, EBL brand (according to the research I did)
What are years of safety compared to an hour of entertainment? You chose wisely.
In all my houses, the smoke detectors have been hard wired and the 9v battery merely serves as a backup in case power is out.
