Odyssey batteries are about as good as you can get these days, with shelf lives of a few years, properties of deep cell technology, ie, they can survive deep discharges w/o issue and plenty of cca's. I will certainly make the change from my stock battery a little down the road.
An interesting thing to note for those of us in the States, Sears Die Hard Platinum batteries are rebadged Odyssey's, and a fair bit cheaper. Unfortunately they don't come in a M3W size, but if your in the market for your normal sized vehicle, it's a great battery.
