Battery Testing ?
My 2009 sat around the dealership for 10 months before I bought it. So far the battery is ok but probably it went flat at least once while there, then was charged up again; that usually decreases its life.
Is there any valid way to predict the remaining life expectancy of a battery? A cranking test sounds best, but does it really help to predict remaining life or just tell you that the battery is good or bad today? If it is useful, how much does the test usually cost?
Thanks!

You should be fine even with the dead episode. I work at a Honda dealer and this happens more than you think and I never see those cars back prematurely for battery issues. With that said, you can buy nice little testers at various parts stores that do a good job with telling you what condition it's in. However the best test is one that includes temperature compensation and those babies are pricey.

After the battery is older, the cranking test might give you a better indication of life, but at this age, the cranking test is just going to give you an indication of how it is today. Most parts stores will do the test for free. It shouldn't cost anything, but in your case, it won't tell you much either.
