This 470,000-Mile Tesla Model S Is Better Than New Thanks To An Upgraded Battery
Briefly

The article discusses the potential for upgrading the battery capacity of pre-facelift Tesla Model S vehicles, allowing owners to enhance driving range despite older models possibly having worn-out original batteries. A case study illustrates a successful upgrade from a 70 kWh to a 100 kWh battery pack in a 2015 Model S, showcasing the practicality, cost-effectiveness, and challenges inherent in the process. This upgrade is feasible for cars built before 2021, but it requires technical knowledge and can come with error messages during installation.
The battery pack can be upgraded to one with a higher capacity, which will, in turn, lead to more driving range.
A used Tesla Model S can be a bargain if you're willing to live with the fact that its high-voltage battery may be on its last legs.
