Gene,
Interesting results...It appears that the 2005 batteries do match the power curves in the documentation so it is surprising that the 2004 batteries produce better performance than the new batteries. It is pretty odd. One of our parents is working with SnapOn Tools on battery check instruments and brought in an impedance checker that they make. We ran impedance checks on all of our batteries (some more than 4 years old) and the recent batteries even back to 2001, maintained their specified impedance. The oldest battery we have still only measured about 20 mOhms after all this time.
