I've dealt with Optima batteries before, especially in the car audio scene which favors them as secondary batteries for buffering large car audio systems. Usually when people report premature failures with them it is because of two primary reasons.

1) They are using a yellow optima, instead of a red optima as their primary (starting) battery. The red ones are starters, the yellow ones are deep-cycle. The deep cycles ones really dont like to be discharged and charged rapidly, which happens when used as a starter battery.

2) Over-charging. If you have a flaky regulator, or over jealous battery charger that cooks the battery, that will for sure reduce the life of an optima battery.
