It IS a group 41, and does have a plastic cover, but the terminal adapter
doesn't seem to fit into the cover.  Here's what it looks like:

No matter how I turn the terminal adapter, it doesn't fit inside the cover.
As you can see, part of the terminal cover is broken, and it doesn't shield
the adapter completely.  The old cover fit perfectly.  Maybe I should have
grabbed it off the core battery.
