Changed my standard battery before I went away this year. Original would not stay charged, unless it was the Optimate.
New one has been no problem, but I do keep all of my bikes on Trickle chargers. Never had a problem, with them but I do not run the optimate, through the plugin point,On the XR. I use a permanent plug attached directly, to the battery. Avoids any problems with the canbus system that way.
