My 2008 1.5 battery has always been a bit on the low side with about 177 miles on a standard charge and a CAC of 144. Since having the car I average about one range charge per month and have run the same tire (brand) for the past 16,000 miles. Then this summer my range crept up to 180 miles and my CAC increased to 148. After being steady at 144 for more than a year. I had a 200+ mile trip yesterday so decided to fully test the range for the first time and see if the range increase was for real. I did a best ever of 240 miles 25 miles farther than I have ever don on a single charge. And another weird quirk is my power consumption for this same trip I have done a dozen times was a record low. Previously on the way to Knoxville the lowest power use has been 221 watts/mile but yesterday it was 201. I have driven several times on a similar day with no wind and comfortable temperatures. The road normally has light traffic and I normally set the cruise on 50 which is the limit on that road. Has anyone else seen their range increase? In plotting my standard ideal miles I now have a slight positive trend over the last 19,000 miles.
