Purchased it at autozone on 08/04/2021 for 159.99 and 22.00 core I got a new car tired of fixing the other one so I took battery out that I bought it for and junked the car I used it for two days still have receipt and under warranty under my name and phone number at autozone but you can’t return stuff like that so will negotiate without core it was 181 or 182 plus tax but I had a old battery I have them for the 22$ core fee
