2014 R nine T battery replacement

Apologies if this is a repeat but search found no results. Anyone able to tell me how to access and replace the battery on a R nine T? Manual just says take it to the dealer and I don't have a service CD for this one. Poking around under the seat looks like I have to dismount the tank but find it hard to believe BMW would mis-engineer to that extent?
 
The tank has to come off. Not the first bike BMW designed this way.

Preliminary steps for battery removal listed on the service disc include:
Removing rear seat
Removing front seat
Disengaging mount for front seat
Removing both brackets for front seat
Removing cover for intake air pipe
Releasing diagnosis plug
Lifting fuel tank to topmost position
Removing fuel tank


If you can do your own work, labor savings will pay for the service disc in a couple of hours.
 
If your R9T is still under warranty, and you are having battery trouble, I'd contact the dealer. Quality control on the stock battery seems to be weak, some are fine, some die in short order.
 
More in the line of a pre-emptive strike. I have been left standing on the side of the road enough times that I now replace all bike batteries after 2-3 years regardless of performance. Overkill but the peace of mind is worth it to me.
 
I have seen more 1-2 year old batteries that instantly failed, than 4-6 year old batteries. Older ones generally give fair warning.
