Interstate Batteries

the Kirkland ones had a longer warranty too...when Costco near me first started with the Interstate batteries they were my first choice as they had 6 months longer warranty for full replacement than most anyone else for the same battery...and Costco's return/replacement policy is second to none...
 
lol you do know they are made by Johnson Controls/Clarios? So are you saying all JCI batteries are junk? so what brand would you recommend? are you sure its not a JCI?? your experience buying "hundreds" of cars that have been sitting for who knows how long in the insurance auction lots speaks volumes...
I think most are made by JCI (now Clarios) but not 100%. Their website mentions a few companies, one being Exide. The Interstate catalog lists a zillion battery sizes and capacities. You only see the common ones in shops that sell Interstate. I think you can order others. I'd guess most sizes are made by Clarios but some odd sizes by Exide and others.
