When I say that the current wandered, I mean that it dropped to 8.5, rose above 12, then dropped again, over about an hour.
I let the batteries rest for about 10 minutes before the 12.3 reading, so maybe not a full rest.
I took hygrometer readings when I first got the batteries. They averaged 1.275, with a range of 1.260 to 1.300, but I haven't figured out how to get the same reading twice in a row off the same cell. Yes, I know you have to fill/empty a few times before reading, but the readings are still inconsistent.
My second charge pass is now at 7 hours, the current is 5.1 and not dropping.
