AlarmTag battery life claim seems almost too good — anyone know how long it actually lasts?

I don’t really buy the multi-year claims. I’ve had mine about 10 months and it’s still going, but I’m not holding my breath.

I feel like even if it’s not the full multi-year thing, it’s still way less annoying than having another gadget to plug in every few days. I’ve had mine for a while now and haven’t thought about the battery once, which is basically the whole point for me.

I get why people are skeptical, but honestly the no charging thing is the main reason I’d pick it over something with a USB port. Even if I have to swap a battery every year or two, that’s still way less annoying than remembering to plug it in.

I’ve had mine for about a year on my keychain and it’s still working fine. I don’t really test it often, but I figure if it dies, I’ll just toss a new battery in. For something I barely think about, it’s good enough.

Probably fine for a couple of years at least if you’re not setting it off. I’d just grab one and not overthink it.

I’ve had mine for over two years now and it’s still working. I barely think about it. Battery will probably outlast my interest in keeping it on my keys.

I mean, if you’re not pulling the pin, it’s basically just sitting there doing nothing, so I’d guess the battery lasts ages. Probably longer than you’d actually keep the thing on your keys before losing it or getting bored.

I’d just grab one and not stress about it. The battery in these things lasts way longer than you’d expect since it’s basically just sitting there dormant.

I agree with Jackson_H that an accidental pull in a bag is the thing most likely to eat the battery, and that's worth planning for rather than assuming it'll just sit dormant for years. My take: treat the multi-year figures as a best case for a device that's never triggered, and do a quick pull-test every few months so you're not discovering a dead battery when you actually need it. Luna's experience of swapping around 18 months is a good reminder that it varies, so I wouldn't count on a fixed number.
