OK, I ran a couple more auto equalizations and they peaked at 1.295 to 1.300 at about 57F. So approximately 1.286 to 1.291 temp adjusted (80F.)
I couldn't help myself. I hit them with The Beast for 3 hours. (Only took them to 16.2v. My first set of GC2s.) This brought them all to 1.300 at 60F with one of them 1.305. Therefore a temp adjusted average of about 1.291.
So I'm going to call it about 15% worth of baked on sulfate on a battery with a same-month date code. I would say it is highly unlikely that the batteries left the factory fully charged.
Therefore I believe I have corroborated MEX's information... at least for this "big" sample of 2 batteries.
