I can safely say that, as I know only enough to be dangerous, I probably do not Know What I Am Doing; I also do not have access to any such special equipment as you describe.

Assuming that 0.1 V is indeed low enough to indicate the battery may have entered a state of permanent discharge, is there any credible risk of this bomb-like state being entered through regular attempts to charge it in the machine? I now have software which could in theory revive the battery if there's actually anything left to revive, but I would rather not make the attempt if it might reduce the machine to slag in the event of unfortunate chemistry.

I kind of need an answer to this before I can know how best to proceed. I am not made of money and will only attempt recelling if there is no alternative, meaning I want to try EMMpathy and the Lind utilities first (ideally I'd have a copy of the Apple one to try as well), but as I said -- I only will try that if I can be reasonably sure it won't destroy the machine, which on my budget is pretty much irreplaceable.
Charging it in the machine? No problem, because the hard-wired safeties will kick in before there is an issue. Just don't expect to get very far.

The potential for molten slag only happens when one starts using exotic methods to try and get them to come back to life which either eliminates or disables all the safeties.
