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
issues trying to run the machines without? (I'm not inclined to replace
batteries unless I have to, just so I don't have to worry about replacement
again in x years time)
cheers

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. You could test it, but don?t
expect much. As for what is stored in there besides date/time, a quick search shows that
it is likely storing data on startup disk ID, AppleTalk status, monitor settings, volume,
mouse speed, and energy saver settings.

Jules,
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.

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.
You might want to run some wire for a socket out of the case if you're going to do
that regularly, since it can be a pain to get in there on many models?and not just on
compact Macs, either, though they're obviously tough.
