Left my 2010 Prius II at a parking facility in Chicago for just over two weeks. Upon return, the 12 volt battery was completely dead. After a $50 jump start, returned the car to the dealership for assistance. Their report:"everything is fine and this is common for the Prius as there are numerous computers that are running as well as SKS". BTW, SKS can not be easily turned on and off in the 2010 series. According to the dealer, Toyota's position is that anything over 10 days of storage with no driver activity will result in a discharged 12 volt battery. Both the dealer and I looked in the owner's manual and could find nothing describing this situation, but apparently they have a service bulletin that covers it. One possible solution when parking the car for an extended period is to disconnect a lead from the battery but that would require me to climb through the back seat area and manually open the hatch door to gain access to the battery to reconnect the lead. Another idea would be to pull a small fuse called the "short pin" located in the center of the main fuse box. Both ideas are rather cumbersome to say the least. Anyone have any other ideas?
