I'll likely jinx myself, but I put in an Odyssey battery on my KLRZ650 in 2010 and it's still going strong. I installed a "marine quality" battery on my boat in 2011; again, still running strong. Car battery is at 6, maybe 7 years? I'm no expert, but the common denominator is that I live in the northwest with little humidity, mild winters and summers...and all three are used consistently or on battery tenders when not used (boat during winter, motorcycles all the time when parked).
The '17EX still has the original battery at nearly 4 years--I realize that they give little warning when they go, but based on my experience with the others, I'm reluctant to replace it as a matter of course.
Seems to me that batteries like stable weather without the extremes of cold/heat.
