You know why it does this right? Lol. If you look inside by the air holes you will see 2 cut outs on either side, those cut outs are for the 2 negative posts. Unless you already knew that then nevermind lol.
OMG. I had ruled that out becasue I looked at it from an angle and it didn't look like the posts were touching it (it's just a tiny portion of that dropped inlet that stops it). Don't mind me, I am just happy to have a good atty.
