I couldn't tell you about all models/years of Ford but some in the last decade have a standard tray, plastic dust cover cap on top, and insulator sleeve around the sides of the battery, no sealed plastic container.The Ford appears to be in a plastic sealed container with a lid on it.
I been using this battery Mat above the battery tray to protect the metal and any items near by. It is suppose to neutralize any liquid that comes in conatct with it.
