Just for the record I recently went on a 1 month vacation. I got back to my V within 2 weeks. I did not disconnect anything prior to my departure. No problem starting the car at all. To top it off, my 2011 Prius III was left idle for 1 solid month. Again, no problem starting the car on my return. After all of the horror stories about the effects of inactivity on the battery, I was very surprised I had no problem, especially after 30 days.
