I see several reasons listed in the first link in your comment.

Maybe something like https://ceenr.com/ ? I've never used them personally.

Google has finally pushed the source of the Pixel 4a battery update: https://android.googlesource.com/kernel/msm/+log/refs/heads/...

You can run this:
adb shell cat /sys/class/power_supply/battery/serial_number

Wow, that is exactly what I was hoping to do, but I wasn't able to figure out more than 1 or 2 of those steps. Thanks!

Image.lz4 is definitely a Linux kernel, and it's definitely changed: https://android.googlesource.com/device/google/sunfish-kerne...
Would changes to external closed-source binary files change the kernel image itself? There are kernel modules in that commit but it looks to me like they all come directly from here: https://developers.google.com/android/drivers
Google does provide detailed instructions for downloading all sources for the kernel, and I didn't see any changes since 2023 to any source files: https://source.android.com/docs/setup/
Thanks for the extra places to look. I'll check them out.

Why not? The kernel seems to handle low level charging and battery logic, for example: https://android.googlesource.com/kernel/msm/+/refs/heads/and...
I'm not hoping to argue, only to learn. This isn't my area of expertise.

I'm going through the kernel with Ghidra but not very good at it and not having much luck.
I do have an idea about what it's checking to determine if a battery is affected, but I don't have enough data yet to know if it's just a coincidence.
