Looking for high-capacity AA rechargeable battery

If it's a bare cell you'll want a protection board, something like:

(that appears to be the same as the Aliexpress above - but 4x the price)

A common battery connector is the XT60, which can be found on chargers like this fancy one:

Worth doing. You can't be the first one to have this problem. Maybe there is a better solution like replacing the sensor with a lower power one.

If we had the controller/motor unit or other identifiers, maybe the excreble design has already been discussed somewhere.

The safety switch housing, may have a part number on it too.

"You can't be the first one to have this problem."

Agreed. And you know what a motivated customer base can produce. Answers.

A lot of these are manufactured by a big company and then rebranded by the installer (big or small). The installer may not have much clue beyond picking parts from a brochure. Then there is this kind of stuff:

I'd have paid more attention to that site if any of the images displayed. But they just show - all of them - as the blue question mark. Hmm, perhaps that's a Safari problem, I can see them in Firefox.

I can see there's more research required.

The newest graphical fetish is .webp instead of using a .jpg .

Is Safari still supported ?

Paul

These call them selves .jpg but neither Safari nor Preview (this is under Catalina) can open them. My file server is running Monterey and Safari there can open them. Perhaps I should try copying that Safari version onto my Catalina system.

That's a bizarre question.

They're webp but for some reason suffixed by .jpg_.webp

It's a good question, because of Apple's insistence of shipping Safari updates as OS updates. Catalina was superseded in November 2020 so its Safari (13) won't have received feature updates since then, and it's the next version of Safari (14) that got webp support.

You can't upgrade Safari separately because it's baked into the immutable OS volume. Not sure whether copying the application to another location on Catalina will work, but I'd guess it will depend on system libraries elsewhere in the image.

Just another one of those things to make you give Apple a pile of money on a regular basis, whether you need an upgrade or not.

The corresponding file with .jpg extension also exists

Yet is also of MIME type image/webp

$ file DC5-5-2-1MM-EU-Plug-US-PLUG-3-65V-1A-2A-Cargador-18650-Lithium-Battery.jpg DC5-5-2-1MM-EU-Plug-US-PLUG-3-65V-1A-2A-Cargador-18650-Lithium-Battery.jpg: RIFF (little-endian) data, Web/P image, VP8 encoding, 1000x1000, Scaling: [none]x[none], YUV color, decoders should clamp

So it sounds like the MIME type is right, it's just the extension that's wrong.

Theo

Well, you can always use a different browser.

I thought all browsers on Macs were required to be a "GUI wrapper" that uses Apple's WebKit as the engine?

This isn't always the case.

So it is still supported then. Which was the point of muy comment. Not supported in a way that suits me, obvs.

I did try and no it needs a later OS version.

Not that regular. I can upgrade this Mini to Big Sur, Monterey, Ventura, or Sonoma, without it costing me a penny. I just don't want to.

This one I downloaded and Preview didn't like it.

I tried Firefox 119.0.1 (under Catalina) and it opened those funny files OK.

No, that's iOS / iPadOS. On MacOS other browsers are allowed.

(it's not a big deal to switch browser in many cases, but Mac users may not realise their Safari is out of date and can't be updated to the latest, beyond security patches that Apple issue from time to time)

Theo

That was my understanding of at least Safari...|I do know that they cant understand Webm Vorbis/VP8 to save their lives...

You could upgrade it to Linux and have an even better experience

In the old days, Firefox was a .dmg and that's what I used to use. Because the Safari at the time, was a "50% browser", where 50% of the web sites did not work quite right. I tried to use Safari, to encourage them, but it just wasn't a feasible solution.

Today, you don't really know what these are compatible with, by just looking at them like this. A dmg is a Disk Image, and it's an archive.

bash:/mnt/d$ file XUL XUL: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit x86_64 dynamically linked shared library, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|NO_REEXPORTED_DYLIBS|HAS_TLV_DESCRIPTORS>] [arm64]

bash:/mnt/d$ file firefox-bin firefox-bin: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit x86_64 executable, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|BINDS_TO_WEAK|PIE>] [arm64:Mach-O 64-bit arm64 executable, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|BINDS_TO_WEAK|PIE>]

That's not something that would run on my old PowerPC Mac. That should run on an Intel Mac, or an M1 Mac perhaps.

My mentioning support was not a FanBoi slam, I've done time on Macintoshes and bought the TShirt. There is an old MacG4 QuadNostril right at my elbow. Hasn't been powered in a year or two or three. It serves as a stand, for the computer on top of it :-) Pecking order. The highest computer stack is "2 1/2 computers" high.

Paul

Both, in fact. When I build my apps I create single-binary versions and give the user the choice of downloading an X86 version or an ARM version. And easy to test here as SWMBO's Mini is an M1.
