I used Optima batteries in a studio truck (4 at one time). They gave me long life, and didn't make a mess, most lasted over 4 years, so no complaints from me. The one in my cobra is going on 4 years old and only went dead on one occasion when I left the blower on for 3 hours with the motor off.
I like them because they are clean and don't vent a lot of acid into the car.
