Kirkland and Interstste

Agree the 100k month battery and warranty great. Replacing mine now due to cold weather and it is six years old. And yes, finding interstate has replaced the Kirkland brand in the stores and I see they only now have a 36 month warranty even though price has gone up considerably.
Previous Review: Kirkland Batteries LAST!
Next Review: Dead after 2 years but thankful for Costco's warranty.

Latest Costco Car Battery Review
Have a Kirkland Signature battery in my 2004 Chevy Cavalier with 133k miles. Sticker shows the battery made 7/11 and I bought it August 2011. Almost 6 years later, it's mostly working but starting to wane.
