You've been sold by the marketing if you purchase an Interstate. They don't make any batteries and they charge a premium price for something that they slap their name on the side. Furthermore, when you need warranty assistance.........clearly, you get the thumb.

With the Autozone Duralast, you get an 84 month warranty that's good at any store without any BS and without a receipt. At $90. it beats the Interstate hands down.

I can vouch for the Autozone battery.

We run an Autozone battery in my wife's Volvo S70. Our four year old twins are notorious for leaving on the rear vanity lights, which ran down the battery within the first year or two.

Autozone tested it in their battery tester, it wouldn't hold a charge, and they gave us new one, no charge.

We didn't even need a receipt. They were able to look us up in their computer with our name / phone number / or address.
