just thought id put this out there for people who search for what others have experienced with the optima yellow top. i bought the battery in march of 06 and had it in the z until october of the same year (which is when the z was parked for the winter). i disconnected the positive and the negative terminals for storage. the following year i didnt drive the z at all as i was in the middle of various projects and had a lot going on elsewhere too. by the time i got the car ready to drive in september of this year, i took the battery to a shop to have them charge it up. unfortunatly the battery can no longer hold a charge and after driving it for a few days it just gave up. i took it back to the place i purchased it from which ran a few tests and confirmed that it was indeed dead. they then told me that unless i did a lot of offroading where vibration is a concern, then optima isnt really the best choice. so it was an expensive lesson considering i only got ~ 7 months of use out of it. so for those considering it, id advise against it. you can get other batteries with just as many amps for much less money, with much better warranties.
