The D47 group size is commonly listed for the 2016 Corolla, but I'd verify against your own battery tray and terminals before buying, since specs can vary by trim. Check the owner's manual or the label on your current battery for group size, CCA, and terminal orientation, then compare those numbers to any candidate. On AGM versus flooded: AGM helps mostly with start-stop or high electrical draw, so unless your car needs it, a standard flooded battery in the right group size is usually fine. I can't speak to long-term heat performance in your area, but matching specs yourself beats trusting a counter person.
