There's nothing stored in the Parameter RAM that won't be restored to a default
state by the OS on boot.
Macs generally won't boot without a PRAM battery though, so if you're storing
your systems without one, you'll need to replace the battery before use.

No - go ahead and remove. The battery retains the PRAM data, which is
generally not a user-accessible feature in the way CMOS RAM is on x86. The
PRAM will be restored on next boot - but obviously, some things (like
virtual memory) will need to be re-enabled. Not a big deal at all.

You just made me think that I need to go check on some of my stuff and see what
the batteries are doing… Been quite a while since I used a lot of them.
On an old Mac, quite often the reason for a machine to not boot at all would be
a dead PRAM battery, so complete removal may not be an option. Y
So I'm working my way (more slowly than I probably should be) through my
systems, ditching ancient on-board batteries before they leak...
In the case of the Mac SE's, are there any critical settings which I should
make a note of before removing the on-board battery? Should I expect any
issue
