I am coming up on a year of ownership in November and about to cross 30k miles - ~20k on the current battery (1st one was replaced @ ~11k). I generally start a max/range charge just before I leave on my weekly commute from MD to NJ to top off - it never sits at 100% for any length of time. I also supercharge twice per week at DE - once heading north and once heading south each week. I recently noticed that a full charge only gets about 256 miles - 96.6% - a 3.4% drop from 265. I am going to start to track it more closely and plan to discuss with the service center when I stop in for the 32.5k checkup. Any other high mileage drivers having a similar experience?
