I bought a new battery for my 2008 TW. Luckily, I didn't put the battery in the morning I was going riding.
The new battery is much smaller (so I used folded cardboard to secure it).
In addition to that small speed bump, The batter connection bracket wasn't threaded either for the screw that secured the positive and neg to the battery, so I just used some zip ties to secure them nice and tight.
You should have received some small threaded inserts with the battery. They go in the hollow area under the terminals and the screws thread into them. They're usually packed with the vent tube and new bolts. I'd go back and raise heck.
