Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface.
  • Turn off all accessories (lights, climate control) to minimize energy draw during the inspection.
  • Tools Required: Tesla mobile app, access to Tesla service center if needed.
2. Battery Calibration
  • Fully charge the battery to 100% using a home charger or Supercharger.
  • Drive the vehicle until the battery level reaches 10% or lower to fully deplete it.
  • Recharge back to 100% without interruption.
  • This calibration can help the vehicle’s battery management system accurately assess the battery's capacity.
3. Battery Health Assessment
  • If the battery continues to show erratic behavior, schedule a service appointment through the Tesla app.
  • Technicians will perform a detailed battery health analysis.
  • Tools Required: Tesla service diagnostic tools (handled by technicians).
