Decoding Tesla Battery Degradation Over Time
Keep your battery charged between 20% and 80% to avoid excessive wear and tear on the battery. Avoid exposing your Tesla to extreme temperatures, as this can cause the battery to degrade more quickly. Regularly check your battery''s health using the Tesla app or by taking your car to a Tesla service center. Cost Implications
