Any tips on how to reverse this? A 3 stage charger is definitely on the list now...

In case its just your multimeter, test it on a AA battery and see if you get a positive readout.
It can be revived as Rob said, i use a similar method to revive AA rechargables. Though i fear the batterys capacity wont be as good before. The positive and negative electrodes have different chemistry's and should be charged accordingly.
