The two new batteries I ordered arrived - these are identical to the four I was asking about the IR of above. I checked the IR of the new batteries and one of the old ones after letting them sit overnight with the other ones so they'd all be at the same temperature (~75 F, been hot here recently, even the basement floor has warmed up). The highest cell IR in the new ones measures less than half of the lowest cell IR in the old ones. Much more inline with what I was expecting, I'm guessing I'm in for a real pleasant surprise this weekend when I throttle up with a new battery.

I guess the higher IR of the old ones is just what comes of a couple years storage at storage charge in the 60-75+ temps in my basement.
