Bought this cooler, battery was out of stock FOREVER. FINALLY got one, open up battery compartment, and battery doesn't fit? I took a closer look and it looks like my fridge is either fake or I was given some sort of prototype product? MY fridge looks NOTHING like what is in these other photos and there is no way I can tell to add my battery. I tried reaching out to customer service - no response. Sadly I'm beyond the point of attempting a return.
