available for free.
Some may disagree , but i upload stuff like this to the Internet Archive.

That sounds like what I remember.

My understanding is that RIFA is a brand of
capacitor which had a model like which is notorious for failing after time and they seemed
to be common in the '90s.
Not sure that IBM would use cheap *anything* in their equipment.

A word of warning, the "inertial rotation" procedure was great for smaller
drives, but you may break your arm applying this to an ESDI :-)
I don't know the state of the bearings. Is
there anything that I can or should do for them?
Aside from dismantling the drive, not really. Just cross your fingers and pray. Usually
not a problem. I have an ST225 which had been powered off for two decades and it came up
fine in my DEC Rainbow!

ACK
My assumption is that the Model 80 has been
powered off for years, if not a decade or more. It's on the older end of a five
computers I picked up from someone >who wanted them hauled away. I'm not holding
my breath that they powered the PS/2 on anytime in the last decade. ;-)
It is my belief that these batteries should still be available from somewhere. If I think
of it when I get home, I'll dig out the box and relay the model number. Provided that
the box is still where I remember.

Thank you. You're sharing things that seem
familiar. Which is appreciated because it means that my memory isn't that far out of
calibration or bit rot.
