Well, It's been 11 months since I got the car. No problems with the battery. It still has the same capacity as it did when I got it. I'm still getting over 100 miles on a charge. During the winter I ran the electric heater most of the time and it dropped the cruising range to 70 miles but that's plenty for my 45 mile round trip to town.
One thing of note is that the number of electric charging stations is increasing. I found one at Costco, the County Jail, Starbucks and McDonalds as well as a new station at the Rest stop at Vancouver Washington.
They are poping up at many of the rest stops and appear to be installed by the State. Cost to charge is still zero on all these public chargers.
I found an after market site that is making a battery that fits in the rear boot space and provides an extra 50 mile cruising range. Things are shaping up. I've saved 1700.00 in fuel costs this year so far.
