I mentioned that I usually charge to 100% about once a month, but last night I charged to 100% for the first time in 2 months. My rated range on my March 2014 "classic" Model S was 265 miles (range mode on). This is the highest it has been in 2 years, as it usually range charges to 263 or 264. I know it is only 1 extra mile, but the vast majority of owners lose range over time. I not only feel very fortunate, but I never plan to change my charging habits!
