Older automobile electrical system testers used a carbon pile load.
Basically, a big resistor.

they did, except that those are now obsolete.

The mechanic who works on my 2001 Subaru has one with a carbon pile
load.  I know because I've repaired it a few times.  Several of the
auto shops that I frequent also have ancient chargers.  Sorry to
report, but the old stuff doesn't just disappear.

In the olden days they used a high-wattage/low-ohm resistor, like 0.5
ohms at 300 watts to cause the battery to put out about 25 amps (though
as the voltage fell the current fell slightly). You time how long the
battery takes to fall to 10.5 volts and then you have the reserve
capacity. The resistor gets very hot of course.

I found the docs to the load tester the my mechanic uses.  It's a Sun
VAT-40:
http://www.learnbydestroying.com/jeffl/Sun%20VAT-40/
https://www.google.com/search?q=sun+vat-40&tbm=isch
Besides the battery, it also tests the alternator, starter, regulator,
gauges, and parts of the electrical system.  The battery load is an
adjustable carbon pile.

A more accurate way to measure RC is to keep the load at 25 amps. You
can design an active load using multiple MOSFETs.

Yep.  That's what the more modern shop use.  An active load is much
better than a carbon pile.

Of course those get
hot as well, and you need to heat sink them well and distribute the load
between multiple devices.

For all intents and purposes, a high-wattage resistor is sufficient for
testing the reserve capacity of a lead-acid battery. DC load and AC
conductance tests only take a few seconds but they don't give any
indication of reserve capacity. There is little, if any, correlation
between the internal resistance of a battery and reserve capacity.

I don't have much experience with automotive ESR testers.  The few
times I tried one, I found that a discharge curve test was much
better.

Testing the resistance and conductance can tell you if the battery is bad. But that can't tell you what the reserve capacity is.

that's the point.

some do, however, it's a parameter that is not particularly important
for cars. it's also not something that's measured by carbon pile load
testers.

For the record, for anyone attempting to reset the Android Advertising ID
from Windows, Android 11 and below would reset the id to a GUID, or
globally unique ID, (similar to what Windows 95 CoCreateGUID created,
according to Mayayana's kind advice on the Android newsgroup today).\

Apparently "delete" isn't so much a delete as a "zero out" such that the
GUID is of the form (8-4-4-4-12) of 00000000-0000-0000-0000-000000000000.

Has anyone here used WebDav to mount Android onto Windows as a drive over
Wi-Fi?
If so, can _you_ see your Android external sdcard from Windows over Wi-Fi?

I can't.
I can see _everything_ else (including the root filesystem!) but not the sd
card.
(Note I'm not rooted but that shouldn't matter to see the sd card, should
it?)

I attempted these permission-addition commands because the Windows Wi-Fi
mount of the Android file system as a drive doesn't access the external
sdcard yet.
 C:\> net use Z: \\192.168.0.2@8080\DavWWWRoot

I also tried adding a login/password of (foo/bar) but that didn't matter.
 C:\> net use Z: \\192.168.0.2@8080\DavWWWRoot /USER:foo bar

And I tried specifying the root directory:
 C:\> net use Z: \\192.168.0.2@8080\storage\emulated\0 /USER:foo bar
 C:\> net use Z: \\192.168.0.2@8080\storage\0000-0001 /USER:foo bar

At least not when using this free WebDav server on Android to mount Android
as a drive letter onto Windows over Wi-Fi using that Windows "net use" command.
 *WebDAV Server* by The Olive Tree

https://play.google.com/store/apps/details?id=com.theolivetree.webdavserver

The problem I'm having with Android 12 connecting to Windows is that I can
set the WebDav server root to anything I want to in the WebDav server GUI:
https://i.postimg.cc/sxzR0Pg8/webdav01.jpg Mount Android over Wi-Fi

But from Windows I can see everything on Android (including the root file
system) except what is on the external sdcard (even though, on Android, I can easily see what's on the external sdcard).

Using this adb tutorial to check if permissions are the problem, I run:
 C:\> adb shell pm list packages | findstr "webdav"
      package:com.zq.webdav.app_free <== this is ad free but more complex
      package:com.theolivetree.webdavserver <== this is the one I'm using
 To list its permissions I can run this but it didn't find any permissions.
 C:\> adb shell pm list permissions | FindStr
"com.theolivetree.webdavserver"

This "might" grant it permission to read external storage:
 C:\> adb shell pm grant com.theolivetree.webdavserver
android.permission.READ_EXTERNAL_STORAGE

But, unfortunately, even though I can see the Android root file system from Windows (with Android being a drive letter), I can't see the external
sdcard for some reason. What's odd is I can see literally everything _except_ the external sdcard
from Windows with Android mounted as a drive letter over Wi-Fi.

Has anyone here used WebDav to mount Android onto Windows as a drive over
Wi-Fi?
If so, can _you_ see your Android external sdcard from Windows over Wi-Fi?

In summary, the situation is thus for mounting Android to Windows over
Wi-Fi:
a. I'm not rooted (and yet I can see the root file system) as a drive
letter.
b. The WebDav server _says_ it will mount Android over Wi-Fi as a drive
letter.
c. But _only_ the external sdcard will not show up in that Windows mount.

Why?
What's the solution?

Could you have mounted both the internal and external storage using two drive letters Z: and Y:?

SOLVED!

Thank you for that purposefully helpful kind & astute suggestion!
https://i.postimg.cc/BvJdKWzt/webdav06.jpg Both sdcards mounted

Following up on your excellent advice, I mounted the entire internal sdcard
over Wi-Fi as Windows drive letter Y: using one Android webdav server set
up to use port 8080... While simultaneously mounting the external sdcard over Wi-Fi as Windows
drive letter Z: using another Android webdav server over port 8081...

I don't follow a lot of what you did but find it interesting you could do it, not that I would though.  What I can get off my phone with a simple cable works for me.

A USB cable is fine, and, in fact, works great for file transfer.
but it doesn't act like a Windows drive letter, nor an Android mirror.

a. This mounts the internal sdcard as a drive over wifi on Windows:
   C:\> net use Z: \\192.168.0.2@8080\DavWWWRoot /user:foobar snafu

b. This mounts the external sdcard as a drive over wifi on Windows:
  C:\> net use Z: \\192.168.0.2@8081\DavWWWRoot /user:foobar snafu

c. This pairs Android to Windows over wifi for mirroring & control:
   C:\> adb pair 192.168.0.2:54321 123456

Here is the result, where I don't know if it gets any better than this!
https://i.postimg.cc/BvJdKWzt/webdav06.jpg Both sdcards mounted

I do have a file explorer app on the phone that is in itself a web server and when started you can go to the http address the app displays and browse your files if you want to do it over wi-fi. 

Again you bring up a GREAT question, of whether a WebDav server is
the same thing or if it's completely different from an HTTP server.

I don't know. Does anyone here know how a WebDAV server differs
from a plain old HTTP server? Are they one and the same?

If they're the same thing, all you need to do to make your Android
phone (or iOS phone for that matter) a drive letter over Wi-Fi is run those "NET USE" commands listed above.

 Of course all of what I'm able to do is not at the lowest level of the phones file structure.  I see no OS of any kind.

What I see is the entire Android phone from Windows over Wi-Fi, at least as far as I know, but I only have write permission to the sections of the phone that you'd expect to write to.

As far as I know, you can't get much more power than I have now.

Congrats though.

Thanks. I hope others benefit from the knowledge and I very much appreciate that you helped me solve the problem of _simultaneous_
access to both the internal and external sdcard, thanks to you!

Here are some of the screenshots for those interested in this power!

Can interfacing a smartphone to Windows get any better than this?
https://i.postimg.cc/BvJdKWzt/webdav06.jpg

Today I solved _all_ the problems I had run into, thanks to the advice from
other helpful intelligent people such as Andy Burns, Herbert Kleebauer, Big Al, et. al, all of whom are who make Usenet a valuable adult
conversation where ideas are exchanged so we all benefit from the result.

1. Over Wi-fi
2. Using only widely available free tools
3. I can now easily mount the _entire_ Android device
4. both the internal sdcard (including the root partitions!)
5. and the external sdcard, simultaneously, 6. each as their own Windows drive letter 7. while at the same time being able to mirror the Android phone
8. and control the Android phone using the mouse & keyboard
9. while simultaneously sharing the two clipboards between them
10. And being able to slide files back and forth at will

My question to the group at large simply is whether there is anything else
that we could possibly want in terms of complete Android/Windows sharing?

Note all of this is done
a. WITHOUT any login to anything!
b. WITHOUT any connection to the Internet!
c. WITHOUT paying a penny for tools

Does it get any better than that?
