I think this is why smoke detectors take 9-volt batteries now.

[-] DannyMac@lemm.ee 9 points 2 years ago

Haven't they always taken 9v?

[-] Fredy1422@lemmy.ml 8 points 2 years ago

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

[-] GladiusB@lemmy.world -3 points 2 years ago

9v are just two AAs wrapped together. So not surprised.

[-] randombullet@programming.dev 3 points 2 years ago

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.
