Tesla batteries retain over 90 percent of their charging power after 160,000 miles, according to data gathered by a Dutch-Belgium Tesla owners group. According to its survey of over 350 owners, the EVs dropped about 5 percent of their capacity after 50,000 miles, but lose it at a much slower rate after that. If the trend holds, most Tesla vehicles will still have 90 percent capacity after around 300,000 km (185,000 miles), and 80 percent capacity after a whopping 800,000 km (500,000 miles).
