The 40K miles and 2 years early failure condition is presumably heat related.

If you are looking at a 10 year old car with 160K miles, you're not talking about any "snow bird" effect (160K is my average across the ~250 batteries). The failures I would attribute to "snow bird" effect can be counted on one hand.
