The only other strange thing I'm noting is the battery affecting
performance. If I swap batteries i.e. take the battery out of my
original and replace it with the battery from the spare laptop, my
original's performance slows down quite a bit, applications are much
slower to open, etc. As soon as I swap batteries back to their native
laptops, the problem goes away and they are back at their speeds. My
only guess for the slower performance after battery swap is that the
battery isn't original either. Although all the markings are "Dell", it
says "Made in China" where my original battery doesn't say on the little
white tag, just date of manufacture. Also "cell made in Japan/ further
processed in China" and on my original laptop "battery cell made in
Korea / assembled in China". So maybe it's an original battery in both
cases, not sure, but I wonder why performance is so much worse when I
simply switch the batteries between the laptops? Seems odd. Now if I
keep them both plugged in, there is no sluggishness after the swaps.

Laptop batteries only last 3 years. You bought a used laptop. The
owner probably figured they wanted a newer and faster laptop and wasn't
going to waste money on getting a battery for their old one they
wouldn't use and were getting rid of, anyway.

Keeping the laptop plugged in means the battery isn't being used to
supply power to the laptop. Get a new battery for the used laptop that
you just bought. Batteries are often required when buying used laptops.
If batteries are not replaceable in a notebook or tablet, don't buy a
used one.

I think I found the issue(s). Doesn't make sense to me, but I have
actually heard of folks running into it. It seems that even though
these are nearly identical laptops, I can't either swap batteries
between them or even power supplies. If I do either, strange things
start to happen. For one, the power light on the front starts blinking
4 red and then 1 white if I try not using the batteries in whatever
laptop they originally came with. As long as I keep the batteries in
their original laptop along with power supply, both run fine with or
without power supplies.

Almost all lithium batteries, maybe all of them, are made in China.

I guess the only positive thing of note is that I was able to simply
install my back up hard drive from my original laptop in the spare and
it started up and operated normally. The spare came with Win 10 on a
256 GB standard hard drive, and I just wanted to see if I could just
install my original hard drive clone onto a separate hard drive (which
is 500 GB), plug it in and see if it would work. I double checked first
to see how close laptop configurations were and I figured the spare
would work this way and it did.

What OS, if any, came on the used laptop that you bought? If it wasn't
Windows 10 (and the same edition) then you just violated the licensing
for your instance of Windows 10. Naughty naughty.

The spare I bought had Win 10. Since I'm not ready to use it, I just
pulled the drive and replaced it with a clone of the drive in my
original laptop. That drive has dual boot with either Win 7 or Ubuntu
selection at boot up.

However, since users rarely buy a new laptop to then wipe its drive to
install a different OS, the used laptop very likely came with an OEM
license. That means you took the OEM license from one laptop to use on
another, so that one license is deployed to two devices. You would have
to find the OEMer's (Dell's) EULA on the OS they image onto their
laptops to find the terms and restrictions therein (good luck with
that).

Luckily, I don't have Win 10 issues yet to deal with, but I suppose the
day will come one day soon. For now, I'm happy with what I have as long
as I no longer try to swap out batteries or power supplies between the
two laptops.
