Directly charging over-discharged li-ion cells with my bench supply. Definitely nothing unsafe going on here.

2.5V is the lowest I'll let one go. Beyond that it hits the bin.
It varies by manufacturer, but the numbers I read are in the 1.5V to 1V range. Though of course you have to slow charge up to ~2.5V.

Of course if these were standard cells I'd bin them, but (non-fake) Nexus 10 batteries are kind of hard to get.

Fair enough. Just be very careful. You don't want to end up with a Note 7. ;3

Eh, that's cutting it extremely close. I've had my share of old batteries turn into blimps in front of me, it's quite nerve-wracking. X3

This tablet actually had a blimp inside until I realized both the slight display distortion *and* the poor battery life had the same cause.
