A Tesla With 470,000 Miles Gets A Battery Upgrade - CleanTechnica

A 2015 Tesla Model S 70D with over 470,000 miles received a battery upgrade using a used but good-condition 100 kWh battery pack. This case challenges common misconceptions that electric vehicle (EV) batteries only last about 60,000 miles or that replacement batteries cost $50,000 or more. In reality, the used battery pack cost $8,500 plus $1,000 freight, and with labor included, a battery swap would be around $12,000. The owner, an EV mechanic, performed the swap himself, highlighting the affordability and feasibility of battery replacements using used packs sourced from wrecked or retired EVs. The mechanic also dispelled myths about battery compatibility, confirming that a larger 100 kWh pack can be installed in older Model S or Model X vehicles without significant weight or performance issues. After installation, the car’s estimated range increased from about 207 miles on the degraded original battery to approximately 280-303 miles with the new pack
