Under the seat......
Plastic tray behind the gas tank, remove the over, the lower tray comes out..comes out......
Before you do any more disconnect both terminals and make sure you do not short them across the frame with dire consequences for delicate electronics. These terminals on my LT were 10mm nuts.
Electronic control module also comes out but this varies with the model. On my LT it was positioned in the recess under the cover and I could lift it to one side and remove the tray. On my RT it is in a slide in shelf under the tray but part of the tray one piece moulding, it has to be disconnected and removed with the tray.
Underneath this you will see the battery with a metal plate across it.
Two crosshead long screws, one each side of the battery go down into the battery support tray.
Unscrew these, plate lifts off but on the right hand side it also holds the coolant expansion bottle in place. It will flop about but should be ok, just make sure when you put it back that the top of it is positioned under the dome in the battery retention plate.
You can now remove the battery but it may take a bit of wriggling to get it out. When you put it back make sure the breather is positioned correctly and also that the coolant expansion goes back correctly.
My seat was a quick detachable one and made the job easy. Looking at my RT I figure removing the seat might be needed to get the battery out.
Sounds complicated but its not.
A little tip. If you have the battery out its a 2 minute job to pull the starter and then have a cup of tea while you check the brushes/clean it....Only 2 allen bolts keep it in plus a 10mm nut on the electrical connection.
