Dave, I have used a motorcycle battery to crank my O-200 in my KR since it was new (14 1/2 years now). I can't recall the exact model right now, but it's a very common one used in many of the bigger bikes, so is readily available at all the discount autoparts stores. I typically get 6 - 7 years service per battery. The down side is that I do have to add water occasionally and I get some acid damage to the paint on the belly from the venting acids.
I have a Odyssey PC-680 cranking the 160 hp O-320 in my home built SuperCub. If it had fit without making major modifications, I would have converted the KR to the Odyssey battery as well. I've only had the Cub flying for a few months, but others using the Odyssey batteries in their RVs and GlasAirs have several years of use on their batteries, so apparently they do have at least a few years longevity.
