Now there are no artefacts flashing on screen, even with the original charger connected, voltage on the battery terminals is 2.65VDC without any AC. With Eneloop, it's 2.9VDC with unstabilized 0.9VAC present.

It's been said and said again, but I'll caution one more time to NOT connect the original charger, even with known good batteries inside. Even a small accidental drop onto the table can momentarily disconnect the cells inside and POOF, your Woodstock is now a doorstop.
