[NDSE]

Wow, they may be put in the wrong battery. Possibly be fine. But, I have a 2017 Hyundai Elantra SE, and I replaced my OEM battery with a Duralast Platinum AGM.

I checked and it looks like the 2017 SE, Value, eco, and Limited needs size H6 48. But, the sport is an H5.

That Duralast Platinum AGM is the battery I ended up with. Sam's, Wal-Mart did not have an AGM battery for my car and would not sell me a flooded battery. If it was mine I would have the tire shop install the recommended battery and sleep well at night.
