I ran the Duracells for a second time - last night for another 40 or 50 minutes. So I am satisifed they are not damaged or defective. And with this "test ride" the cells have been charged for over 72 hours so I guess I can trust them for most conceivable situations.

The only thing I have noticed is that one "pair" of the cells started off at a fraction of a lower charge, and those two cells continue to discharge ahead of the other two cells that were all charged at the same time time in a 4 bay trickle charger......

After over three days from charging - and after nearly two hours of run time, I now have two cells at 1.23 and two cells at 1.29.........good enough for any of my situations....
