I have whatever oreilly's in house AGM battery is and for what I remember, it's made by deka.
You are correct. East Penn builds the O'Reillys Super Start AGM, Deka Intimidator, and the Co-op Extreme Magna Power (in Tennessee). The batteries are the same, just different names.
I have run them for many years in a lot of different vehicles and they have been abused. I will always run them.
Made in the USA in Pennsylvania.
