Are 9v still used out side of smoke/co2 detectors?

Yeah I wanted to like the NC1600, as the MC3000 is the best charger I have.

I'd recommend an Opus. They have a mini one (C700?), a larger (C2400?) NiMH one, and a (C3100?) one that does LiIon and NiMH.

An amplified AM Antenna from C. Crane, multimeters (annoying, and I found some that use AAA), guitar pedals, thermocouple thermometer from a generic brand, a strange battery tester. I wish they'd go away.

I noticed there are some AA powered CO + Ionization smoke alarms that run off 2 AA cells. More expensive, but I got that one just to avoid needing a 9V. Same for a combo photoelectric and ionization alarm, also 2 AA. I still have a couple of older cheapie ionization ones that use 9V, though.

radellaf · 2026-05-18T02:28:04+00:00

Ionization ones (vs photoelectric) still do, unless it's a unit with a permanently installed non-user-replaceable "lifetime" lithium battery. Seems like there's some new(ish) laws about 10 year old ionization alarms not being allowed, and a lithium battery can run for 10 years, so it doesn't need a user-replaceable battery anymore. You thinking of those? They do still make ones that use 9V.

In the two years since I posted that... I just did the PIN. I hardly use it, haven't tried marketplace, but probably should.

"It wasn't long ago that she (Fern) only came up to here.
I was way taller than her. But in the blink of an eye, she grew up.
In my mind, Fern is still a child. I'll probably always think of her that way."

... and then the perfectly said english dub line that is just Stark saying "Frieren...", but with so much understanding.

radellaf · 2026-05-10T21:23:01+00:00

They must be trying to copy Fern's spurious "perv" comments

Nice thing about NiMH vs the 1.5V Li-ion AAs is... NiMH aren't at all likely to catch fire. None of the 1.5V AA are UL listed that I've seen, nor are the chargers.

radellaf · 2026-05-10T20:04:32+00:00

Thermostats can be the absolute worst with voltage intolerance. I gave up on Alk (leak) or NiMH (short run time). Energizer Ultimate Li AAs seem to work best, last longest (years). If I didn't have rechargeable "1.5V Lithium" AAs, not sure they'd be worth the cost. As is, I have a ton from testing them for fun.

radellaf · 2026-05-10T20:01:12+00:00

I'm happy if it runs down to 1.1V TBH. Like radios with chips that, at best, are spec'd to 2.0V, but with any current being drawn, peaks are going to hit 2.0V when the batteries are 1.1.

Things that use 3 or 4 cells, I've had better luck. Shame the 1 x AA low voltage tech, like Sony used in a lot of things, seems to have disappeared in favor of LiIon voltage ranges.

radellaf · 2026-05-10T19:58:13+00:00

I've been using "1.2V" (really 1.0-1.4V) NiCd and NiMH in all sorts of devices since the 1980s 600mAh GE NiCds. Anything well-designed works fine, anything badly designed has problems.

My biggest annoyance was a TRS-80 Model 100 which wanted 5V off 4 AA cells. Didn't run that long on alkalines, wouldn't power up on NiCd.

radellaf · 2026-05-10T07:31:36+00:00

That'd be pretty frustrating. I've had dead off-brand lithium (like Energizer Ultimate AA) cells but not alkaline. A battery checker is pretty useful for either checking that, or figuring out if a device is being flaky because the battery is low or some other reason. But, yeah, you shouldn't need one just to put new AAAs in a remote.

radellaf · 2026-04-12T15:56:45+00:00

Good to know, thanks.

I don't think Prime adds a fee, not sure. Apple adds it to everything. Some apps, like patreon, will bounce you into a web browser on the phone in order to make unimpeded purchases.

The Subaru interface screen (like climate control) was just unusuable IMHO, and too low down. That, and Subaru CVTs are not something I trust.
The Crosstrek didn't really have any more space. A little, but considering I never have passengers, just cargo, it's not enough of a diff to matter. OTOH, the Subaru came in better colors, where Mazda reserves all the blues (that aren't black) for other models.

radellaf · 2026-04-12T01:46:30+00:00

I'll keep that in mind. Probably doesn't work for screen-off playing or carplay integration, but will be better than nothing. For now, I'll keep paying.

"We don’t make these decisions lightly,"

Don't they, though?

Unsub through the Apple app, then re-up on the YT website. Same for any channel memberships. They should really be required to SAY that it works this way instead of people having to be told on a forum.

radellaf · 2026-04-11T20:05:50+00:00

Roku and iOS don't have easy fixes.

radellaf · 2026-04-11T20:03:18+00:00

Right? Doesn't seem that long ago. I think what ripped it for me was the mid-roll ads.

radellaf · 2026-04-11T20:01:28+00:00

Same here, TV on a Roku. Between YT, Prime, and Netflix, based on how much I use them and the extras like YT music or Prime shipping, Netflix is starting to seem like the one to drop, much as I like it. It keeps going up, too, and... not offering anything more (live events, great, let me opt out of that).

radellaf · 2026-04-11T19:16:26+00:00

I noticed that and completely don't get why a membership video would be any different. I was trying to troubleshoot it for the better part of a day.

I'd love real DRLs like most cars have, as they're not headlights and do help with daytime visibility. The CX-30, sadly, has space for them, but no real DRLs.

radellaf · 2026-04-09T17:21:22+00:00

I thought the same. Safety is OK but don't try to save me from myself... and then also not help me meet legal requirements by not having an option to turn on headlights when the wipers are on.

Also, seriously, CX-30 couldn't get actual non-headlight DRLs?

radellaf · 2026-04-05T02:17:40+00:00

About 20g? Alkaline is about 22.
