Costco in Tempe, Arizona Switches from Kirkland Signature to Interstate Car Batteries
To my surprise, I found that on my visit today, Costco had switched from my standing favorite Kirkland Signature brand batteries to Interstate car batteries.
For automotive applications the warranty seems to be a bit less, as I believe the Kirkland Signature batteries had a 36 month full replacement warranty, where the Interstate batteries have only a 30 month full replacement.
Over the years, I have put many Kirkland Signature car batteries in my vehicles and they have done well, especially considering how the Arizona summer is notorious for killing batteries. The warranty exchange was always hassle free, and I drove with confidence knowing I had Kirkland under my hood. I will miss my Kirkland Signature batteries.
Also note that they still do carry the Optima brand high end batteries as well. I have confirmed that the Chandler Costco made the switch to Interstate car batteries, as well.
