What about fabricating a switch for the battery? Anyone familiar with the factory battery on/off switch on Ferraris?

I do also recommend the CTEK charger** especially if you are gone for a week or so during the winter.
*Had the battery replaced on my 2011 X6 50i as well as our 2010 Clubman S
**I "think" the battery on the X5/X6 is an AGM type battery and that is a different setting on the CTEK. Check with your dealer to see if you have this type of battery before charging.
