My Supernova wasn't keeping the time/date so it looked like it was time for a replacement backup battery. After a search on the net I couldn't find any info on it's type or location so, after a quick chat to the guy who calibrates my Supernova, I was fully armed and ready to go into battle. The battery is a 3V lithium button cell soldered to the board. It's a very simple job but it WILL INVALIDATE YOUR CALIBRATION!!! If you want to see how it's done take a look at the instructions that I've put up at
