Thanks for clarifying.... I also heard but don't have any experience that the Opitma's are not as good as they use to be.

Fact or Fiction?

I do know the standard lead acid Trojans are really good batteries.

Well, my experience with Optima have been good so far with 2 Subarus (and Subaru is known for under-sizing the batteries that come on their cars), a Neon, and a Tacoma. Easily got about 6 or 7 years out of them, then we traded the car (batteries never died in my service).

Thanks... I should have tried them in my 6.0 PSD truck. That truck would go thru batteries like crazy. The interesting part is because of this I got several free sets of batteries because of this.

The 6.0 eats batteries. The FICM is so picky about the juice it gets I change mine every 3-4 years on my sick-o. The 6.0 pulls hard on the batteries until it finishes it's start-up procedures which takes 5 minutes or so. The 5.9 Cummins only runs the intake heater in the colder months and even then once the truck reaches 20 MPH the heater goes off and stays off so the batteries don't work near as hard.
