It's in that large black thing in the middle of the motherboard, a Dallas
clock module.

It's replacable, but there's no clearance between the bottom off the
battery tray and top of the clock module to add a socket. On my SLT/286,
since I _have_ no battery, I cut a hole in the aluminum to let the top
of the module stick up.

One "problem" is that the model of Dallas module that the SLT/286 uses
is no longer available because of a Y2K bug. There is a substitute, but
I don't know if the SLT/286 BIOS likes it or not. For now, for mine, I
found a newer Dallas clock module of the exact same part number, but with
a newer battery. I've also hacked the old one to expose the battery leads
and soldered on an external battery connector.

Mine also sees regular use (when I'm home), as a platform for my ISA-based
device programmer (UP600A).
