EA falcons are the cars that come to mind that cook batteries, the cars wound up leaving the factory with the battery in a box, ventilated from above the grill.

The problem was that they where stuck in the front corner of the engine bay behind the headlight with NO VENTILATION.

Your battery should servive behind the radiator as long as it has air flowing over it, just try to get it in the best spot you can with the best chance of getting some cool air from below or around the radiator.
