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.
Get the ones with the built in 10 year battery. Smoke and CO2 combo.
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.
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!
Haha, same situation here. Whenever my partner says she is giving away a toy, my first reaction is "take my batteries (eenlops/EBLs) out!". My older brother was always shitting on rechargeables, but they have been great for me
Yeah, it’s the presence of the partner that complicates things. Likewise I would never let something leave the house without checking the batteries if it were only me.
It’s always fun when I come home and take out some garbage bags because she did a big cleaning, and then the damn garbage starts playing music or giggling at me.
Oh great, so now it’s a question of whether I leave it up to fate or dig through the garbage and go find my little screwdriver. Because for anybody not aware, kids toys typically have a screw to keep the battery compartment cover in place and kid proof.
Fortunately, I’ve only found alkalines the last couple’s times. But my son is 7 so the heat Alkaline Influx happened many moons ago.
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)
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.
I use them for my game controller and my wireless mouse but that's about it.
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.
As a kid I'd always go to the appliance section at the thrift stores my family would frequent to see if I could forage some batteries left in the products. They are almost always nearly dead, but I'd take 15 minutes of Gameboy time over nothing.
My parents rarely bought me batteries, and when they did they'd buy the big packs of off-brand ones that only lasted an hour anyway, so I had no power more often than not.
A little while after the Gameboy color came out, I was able to get my hands on a rechargeable battery pack, and I remember thinking that was an absolute game changer.
I don't miss the days of everything running on batteries.
I do. I have rechargeable aa and aaa batteries. When a battery pack goes bad it's a pita to order/buy/replace. When my rechargeable AAA battery goes bad...."oh, look. I have a dozen more and they were like a buck a piece."
When I was about 10, my mum was addicted to tetris on the GB. I'd get home from school and literally every battery in the house would be completely dead...
I talked to her about it a few years ago, she told me that for about 5 years after she stopped playing she'd dream about tetris more often than anything else.
I just took them from my mom’s dildo collection.
My smoke detectors were all the rectangle batteries. But I pillaged everything else.
We used rechargeable batteries. The tech was bad at that time but I remember it would last about an hour.
Harbor Freight to the rescue!
