Mine lives on the optimate 24/7. I haven't run it since June last year and on saturday morning it started first push of the button.
I think the Odyssy batteries are a bit bigger than standard ones so you may have a tight squeeze getting it in.
I should add though that leaving it standing for long periods will kill it just as quickly as a regular battery.
Cranking current is not the issue with the St''s anyhow, the problem is with the standard cables between the battery (or solenoid) and the starter. Someone in America does a mod kit with some heavier cables which improves things if you are having issues. Simply fitting a bigger battery will allow the engine to turn over for longer but won't necessarily make it turn over any faster as the cables are the limiting factor here.
