Costco had switched from Kirkland signature brand batteries to Interstate car batteries.
While we found no official online information on the said brand of car batteries, anecdotal reports say that an Interstate battery costs $77.10 on average, plus an additional $15.00 core fee which can be refunded upon the return of your old battery.
