[Samba] What happens if I turn the DC off?

I assume I know it ... but I think this is worth being discussed and
At a customer we have 1 samba DC and 1 samba DM = fileserver.
The DC is supported by a small UPS and the battery in that UPS is
getting old and tells me to replace it.
While it might be possible to swap the battery "online" I prefer to shut
the supplied server(s) down and do it offline.
That means turning the DC off.
And now the question(s): will the PCs notice that? Is it possible to use
network shares etc while the DC is offline for about 10 minutes? Or will
the PCs hit problems right away?
I understand that logins might fail, sure, but maybe the authenticated
connections to the DM could be maintained by the DM itself for a short
period of time?
Sorry if I ask obvious things here or show my misunderstanding ... but I
never tried that and wonder what happens.
Sure, a 2nd DC would be much better, I know.
And selecting a maintenance window for doing all this will also be possible.
