What gets me is that this limitation wasn't mentioned during the sales pitch. (Of course, I seldom here problems mentioned while trying to pitch anything.)
Most "normal" people normally wouldn't have a problem with starting the car every 1-2 months. For more than 20 years, I wasn't "normal".

I was in the Navy and my ship was underway for 6 - 9 months at a time. Since I'm single, this meant putting my car in long-term storage inside a fenced and gated lot.
I always disconnected the positive cable before I said good-bye to my car. Never had a problem with a discharged battery.
If I was still in the Navy, I guess you could imagine the colorful language I would use after spending $30K on a car and THEN being told that I could look at having to have my car towed to Toyota and have the traction battery recharged.

. This would need to be done after finally returning to my homeport and anxious to get home!
I realize there is/was a "shorting plug" somewhere in the car to keep the battery from discharging on the trip from the factory/plant. Not sure how long that will keep the battery charged or if it is safe for a user to install it.
