Who makes which battery?

Wow. Never heard of such a thing on a battery. What turds. I've had batteries die before the end the warranty and just went back to the store with my receipt and the core, grabbed a new one, paid any difference between the price and walked out 5 min later. That difference might be $10-15 but not like what Costco is trying to pull. Screw that.

In fact, this is why you cannot go wrong with the Everstart Platinum for $180. Save your receipt, party like a rock star and if it wont put out anymore, turn it back in before it turns 4 years old.

I think a lot of places have prorated warranties on batteries. I don't have a problem with it.

Yes, since the change in late 2022, I have only purchased at Walmart now. The four year warranty is reassuring on their AGMs, but hopefully not needed. In the case of West Coast WalMarts, the AGMs they sell are identically sourced from Clarios as the Costco/Interstate AGMs. Same countries of origin (Korea, Mexico, China, Germany, or USA)

The last couple batteries I bought at Costco are probably going to outlive their warranties though. One expires end of February, the other in June.

Yes, same exact battery. Could be made at any of their plants. Interstates are sold at lots of places outside of Costco.
