I was under the impression that in most reasonably sophisticated vehicles, when you activate front defrost the air flow is redirected. But also, if it's warm enough, the AC compressor is activated to help condense excess humidity in the supply air. I'm just wildly speculating about this though since the front defrost switch is the only thing I've observed to be coincident with these battery failures especially since I almost never have it activated.
