Interesting. Okay 11.5v average/3 ohms yields ~3.8A for 3.25 hours is 12.4 A.H. According to the Enersys data on a PC680, the new battery supports about 4A for 3.2 hours Emacs! It would appear that your test article is pretty healthy. The only other variable is load dump ability. Given the cap-check data, I'd bet the load dump numbers are good too.
