The battery does not cause the amount of current that will flow. That is set by the starter resistance. If the starter draws 250 amps, then that is all that will flow, the battery won't push 550 amps through it.
About 200 amps is normal for a start.

Thanks Harvey, that is certainly food for thought. I'm hesitant to replace the ignition switch and key lock which has been recommended because the problem seems to be related to dissipating power of some kind.
If it "can't" be the battery then what is it that changes when the car is left un-started for several days? It seems logical to me that it's somehow related to "something" losing a charge over time. It's very consistent as far as this goes. If I start it every day it "always" starts. If I leave it for a few days, it doesn't!
