Tesla Batteries Retain Over 90 Percent Charging Power After 160,000 Miles, Survey Finds

According to a survey of over 350 Tesla owners, Tesla batteries retain over 90 percent of their charging power after 160,000 miles. The EVs dropped only 5 percent of their capacity after 50,000 miles, but lose it at a much slower rate after that. Most Tesla vehicles will have over 90 percent of their charging power after around 185,000 miles, and 80 percent capacity after 500,000. Engadget reports: Tesla has no battery degradation warranty on its Model S and X luxury EVs, but guarantees that the Model 3 will retain 70 percent battery capacity after 120,000 miles (long-range battery) and 100,000 miles (shorter-range battery). That's a bit more generous than the one Nissan offers on the Leaf (66 percent over 100,000 miles) for instance. According to the survey data, Tesla will easily be able to meet this mark.Read more of this story at Slashdot.
