I have a 2013 Model S 85. I used to be able to charge at 275 max and now I am lucky if I get 200 max. My range doesn’t last either. If my trip is 40 miles and my current charge is 150, I barely make it home with 50 miles left. My battery is no longer under warranty and it has been tested at dealership to ensure it is not damaged. The results comeback as battery is in good condition. The Tesla technician described the issue of that of a cell phone . With time it will lose its charge. I still don’t know how much it cost to replace the battery when the time comes. I have heard $14,000-$20,000. Does anyone know?
