Prices are getting out of hand. Even at Autozone...

I got the hyundai battery at O'Reilly's.

The others available were Johnson Controls made and I have not had the best of luck with them.

It was slightly larger than the OEM, and I had to cut the jacket/heat barrier.

It is higher CCA, though at 780 vs 660.

I also found out that they only make 3 year batteries in group 48 AGM, so 4.5 years out of the OEM is pretty good.

As an aside, the staff at O'Reilly's was shocked that I knew what model battery I wanted and that I had the application correct.
