"About three times a day, Rich Benoit gets a call to his auto shop, The Electrified Garage, from the owner of an older Tesla Model S whose car battery has begun to fail. The battery, which used to provide several hundred miles of range, might suddenly only last 50 miles on a single charge. These cars are often out of warranty, and the cost of replacing the battery can exceed $15,000." https://www.scientificamerican.com/article/ev-batteries-are-dangerous-to-repair-heres-why-mechanics-are-doing-so-anyway/
