AutoZone Optima Batteries

Does anyone have experience/recommendations for the high priced Autozone Optima Batteries? Are they worth the price?

My first Optima I bought from AZ and my second I bought from Oreillys Auto Parts.
I have been running them for about 4 years now.

Yes they are pricey, but I think in the long run they are worth it.

They seem to have a little more kick when it's really cold (-5).

I also run Hella Rally 4000 and 500 lamps, plus two radios, along with everything else and I wanted a battery that would handle all of the extra load without failing.

For me it was more of a piece of mind than a fancy battery.

I have both the yellow top and red top.

Kinda long winded, but I hope this helped.

I'd actually recommend the AC Delco batteries. The original Delco in my '89 Sierra got 9 solid years use before crapping out, and the AC Delco one that I put in back in 1998 just went on me this past december, so I got nearly 10 years out of the second one. I have a 2400 watt sound system in the trunk of my '84 Caprice and with the Delco I put in there (same one as the truck asctually), I can have the thing going for hours straight and the car starts right up without a problem. I don't know about Optima batteries, but I will swear by Delco. They're a little more pricey, but man to them things take a beating and last a hell of a long time.
