No, the vents DO NOT fit on an Optima. No way, no how.
The best battery to get is the biggest/baddest one from Auto Zone. Their Duralast Gold with 800 CCA and 1,000 regular amps is a good deal at $130 before core. 3 year free replacement (same as Optima) and 5 years pro-rated. When I just bought a new one for my car, it'* the one I got. It'* made by the same company that makes Optima'* too.
