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

I *think* 1.8V is still above the "it's gonna go boom if charged" range, but... we'll see.
Just a few minutes later on normal USB charging it's up to 3.7V. That doesn't quite sound right... the cells might be damaged. Meh.

Might actually be normal-ish though. Charge voltage plots do show 3.7V as a typical "depleted" initial charging voltage.

Huh, weird if nothing's in series and it's a reasonably normal cell chem
