Nope a voltmeter would show bad cells after the overcharge period, this is the procedure that would also be used on antique flooded nicad.
Generally "bad" cells won't come up in voltage and will be significantly lower, some bad cells also will come up in voltage and have no real capacity but this is rare.
After the overcharge period described at 99mpg you can charge and test individual cells that are not quite right, charging and discharging individually.
Many packs come back enough to use even when they are "bad"
A capacitor charger (constant current) could be used in place of the ones on 99mpg with a GFI sort of like this one

Nice dead man feature
But good enough for the purposes of a once or twice off rejuvination.
