If a battery of a given CCA was sufficient, would one with a much higher CCA give longer life?, with everything being equal?

No, equal weight battery with higher CCA is shorter life.
High CCA = more plate surface area = thinner plates for same weight battery.

No. Battery life depends on quality of build. This depends on the purity of materials, including plate construction and strength. Plate anchoring to the intercell connectors, the quality and support of the plate dividers (usually fiberglass mat), and the stability of the case and external connections in it. Venting technology also comes into play. More capacity in CCA lets it produce more amps into a starter longer. The few battery manufacturers still operational create batteries at several quality levels, and sell to both quantity buyers, and small dealers at different price points. It is not transparent at all. If you find a great battery, by the time it fails it is usually not going to be found as the same exact device you were proud of. Jim

No, like others said, it won't help.
Only thing I can add, keep it away from underhood heat if possible.

Good morning, Steve:
Your mention of heat hurting a battery caused me to think about my Deere model 212 lawn/garden tractor. The hood is pretty much closed in and the dash panel area gets so hot I can't keep my knees against the sides of dash if I am wearing shorts. The battery is closer to the engine than the dash is, so it must be really hot. Bad design? Thanks if you can reply with some suggestions.

Depends on how you take care of the battery. Even the best fail if you don't do proper care.
the only thing you can do to get as much use as you can is to keep your tractor tuned so it starts quickly, keep your charging system working correctly, put a maintainer on your battery so its stays fully charged when your not using it over a period of time, putting a rubber based material under the battery will help on the temp of your battery. I cut up an old tire tube to use for that,I have also read where keeping your battery clean helps the life of it as they say dirt collection on battery's will hurt it. most smaller tractors, 45 horse and below 650 cranking amps is all you need to start your tractor. starting or cranking time is the most hurtful thing on a battery. in the winter when i am not using my mowers and the pieces of equipment i take them out and put them in a heated barn with a maintainer. i have four batterys that are 7/8 years old and still going strong. use to never worry about batteries but with the cost now. i never buy a Walmart battery.

Dennis, anything you can do to get it away from the heat will help.
Any place to relocate it?
Garden tractor batteries are known for short life anyway, anything you can do will help. If there is any place to upsize to a small automotive battery, all the better.
You might be able to add some insulation between it and the engine. There is some thin aluminum ductboard type insulation at Home Depot that might work.
Getting some air movement under the hood would help. Just be careful not to starve the engine of cool air, or recirculate hot air back to the engine. It's probably designed to bring cool air to the engine air intake, then discharges the hot air under the hood.

There ain't no free lunch. In order to increase CCA (or amp-hours, for that matter), the storage density has to increase. Something has to be made lighter (thinner case and plates) or crammed closer together (less plate separation). These things are detrimental to battery life.

I buy bigger CCA mower batteries because All batteries begin to fail the day they are made.
Take the smallest and cheapest lawn mower battery (about 200cca) may not last you very long. My theory is that if the battery losses 50% of the CCA that isn't enough to start a mower.
However if you have the largest mower battery possible(about 400cca)it could lost 50% of it cranking amps and do the job of a new 200 cca.
So if both batteries fail at same rate, the larger CCA will have a longer service life.
Go big.

The longest lived battery I ever had a ten year useful life. It was a cheap battery from wal-mart, a group 26 battery. For its physical size it had the lowest rated CCA of the lot. It went into old farmalls, spent time in the dirt car, got me to work, fell off of things, got ran down and even did occasional fence charger duty. Near the end it was hard to get cables to stay tight as the posts were so worn down. After ten years it got to where it would no longer even turn over the riding mower. IIRC I paid about 30 bucks for it new.

Lead acid battery life is shortened at temperatures over 77F.
