It is a battery/clock chip, about $15 from Mouser, Digi-Key.  In my EPI-800
it is a M48T02-200PC1.   The last time I replaced it, Vision micro loaned me
a cable/switch which could be used to set the tach time.

Subject: [LML] VM1000/EPI-800 replacement internal battery?

Does anyone have a source for these internal VMS DPU batteries (EPI-800
system)? Ours is going on 10 years. I should probably replace it.

I am hoping it is a standard electronics DIP type plug-in available through
Mouser, Digi-Key, etc and not a specialty that is only available through
JPI?
