Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface.
  • Make sure the vehicle is in "Park" mode.
  • Ensure that the vehicle is not in use, and other electrical accessories are turned off.
2. Access Battery Health Information
  • On the touchscreen, navigate to Controls > Battery.
  • Observe the Battery Health percentage. A healthy battery typically shows 90% or higher.
  • If the percentage is significantly lower, consider further diagnostics.
3. Conduct Charging Efficiency Test
  • Connect the vehicle to a Supercharger.
  • Monitor the charging time and rate. A slower than normal charge may indicate battery degradation.
  • Note any errors or warnings displayed during charging.
4. Use Tesla App for Further Insights
  • Open the Tesla app on your smartphone.
  • Go to the Vehicle section and review any alerts or notifications regarding battery health.
  • Check the Battery section for additional metrics and stats.
5. Perform a Range Test
  • Fully charge the vehicle to 100%.
  • Reset the trip meter and drive until the battery reaches a low state of charge (around 20%).
  • Compare the distance traveled with the manufacturer's estimated range. Significant discrepancies may indicate battery health issues.
