Ah, sorry, to be clear, I meant overcharging them for side 3 of the obelisk at Laurion. I don't seem to have the option to do so anywhere even after making the cell charger.
Yes, if the power artifact is installed in Astrape, its power system becomes unstable. So any cells you charge in Astrape while the power artifact is installed will become unstable.
Hah, more fool me... I was thinking I would have to charge an already charged cell, given I was overcharging it. All I needed was an empty one. Thanks!
