I've had at least Two Vintage Laptops destroyed by leaking RTC Batteries.
These are miniature NiCads as I remember.

They seem to go green and the Corrosion travels up printed Tracks on the PCB
if allowed to go flat and left for a long time..
I had Tracks and adjacent Tracks eaten right through on the Motherboard rendering them spares only.

Very similar after having stored my old Amiga 600 computer for many years in the loft, several years ago I got it out to check operation and found its RTC battery had badly leaked, seriously damaging loads of the fine track artwork.

Tried repairing it but trying to work out where all the complex double sided tracks should connect to, turned out to be too time consuming so eventually it went to the PC heaven.
