My Costco sells Interstate batteries. They have a 36 month warrantee and Costco does not have the ability to test the battery so mine gets returned every 32 months for a free replacement. They sell deep cycle marine batteries as well so I do the same with my boat.
Have not purchased a new battery in years. Only hassle is that my Costco stopped selling batteries so i have to go to the one on the other side of town.

It's weird.. I drove for 45min-1hr this morning going highway speeds (65+) and it sat for 2-3hrs this afternoon. I sat in the truck for ~15min (key turned ON but ignition off) setting up a dash cam I bought and got a low battery warning on my LCD screen in the cab. I tried to turn the truck on once I saw the warning and it would not turn over (assuming dead battery).

Just went through this with a 2019 Hyundai Santa Fe. Battery would not hold charge for more than a couple of days. I put an amp meter on the battery cable and could not really see much draw. Took it to dealer who had it for several days and came back and said bad battery even though it load tested good at Autozone. Dealer said they see AGMs self discharging when they start to go bad. I am not an expert but they replaced the battery and car has been fine ever since. They did it under warranty and replaced it with OEM.

Pretty sure what's being communicated to us is that he lies to Costco and claims the battery is bad in order to cash in on the warranty, when he knows it isn't, which swindles Costco out of the cost of a new battery
Some people are okay with intentional dishonesty/cheating of others so long as they don't get arrested or fined for it (or if they are cheating a "big company" vs a single individual) while others don't care much for it on principle
