1996 Daytona

Hi all, silly question but I'm new to Triumph, just had this bike today and it started and ran but now the battery is flat now and don't know how to get the seat off, I'm guessing the battery is under there, it's not that I'm not mechanical I've built a Kawasaki H2 special from a frame, it's just rather than snapping something I thought it easier to ask you guys
Thanks in advance

 

Dave just figured it out thanks, it's very low and I thought it might be a helmet lock of some kind
Thanks for the quick reply though
