not a dumb question at all. I took most of my bike apart and when i saw where the battery was i was like wow thats interesting. On my 11 muscle its in there kinda tilted which seems weird. I know its a sealed battery but even those can leak out. enjoy your machine
... is tucked in behind the steering head, lying down, almost flat, and a real PITA to get to. The whole airbox (not just the cover) has to come out to change it but if you're just attaching some gear you can reach the posts without going thru all that. Instructions on removing it are in the Owners Manual. Pay particular attention to how to deal with the rubber hold-down strap.
Hint: If you have the (optional) whooper/siren addition to the Security System, it has an internal battery and raises holy hell if you disconnect a battery cable. Use jumpers from another battery to the POS cable & GND on the bike to keep your neighboogers from shooting you.
