    Does anybody know what might hapen to the HV Battery if the car is not driven for 4 months? Must the 12V battery be trickle-charged the whole time? Can I trickle-charge the 12V battery using the 12V socket in the car instead of taking out all the foam etc to get at the battery on the passenger side?
