you might want to check out rolls/surrette website
they have alot of info and the formula to determine the answer to your question
of course it is tailored to their products but the relative info is useful for other manufactures as well,,, generally speaking.
as the others have stated there are many variables.
in general you will get more kwatt/hrs out using a specific discharge/charge regime.
if you can work within those constraints you can maximize the life of the batteries or get more kwatt/hrs out over their lifespan,but not both.
so it all comes down to what you want or need from your batteries.
for instance, keep them cold and they will last longer, with lower capacity.
keep em hotter and they will deliver more, but at a reduced lifespan
and the list goes on.
having a clear understanding of all the variables and how they effect the battery
lifespan will dictate which method you use to get what you need or want out of them.
or at the very least have a reason to believe you will
otherwise it can be a crap shoot
