Check your Tesla's battery condition by comparing current range to original EPA specifications. Monitor battery degradation and get insights into your vehicle's long-term performance.
This page includes an interactive battery health calculator, comprehensive battery guides, degradation analysis, maintenance tips, and answers to frequently asked battery health questions.
Check your car's display after a full charge to 100%
Enter your Tesla details and current range to check battery health.
Follow these steps to accurately assess your Tesla's battery condition
Choose your Tesla model or enter custom EPA range
Fully charge your Tesla to get accurate range reading
Note the displayed range on your Tesla's screen
Get your battery health percentage and analysis
For accurate readings, charge your Tesla to 100% and check the displayed range immediately.
Cold weather reduces displayed range. Check battery health in moderate temperatures for best accuracy.
Take several readings over time for a more accurate assessment of battery degradation trends.
This is an estimate. For precise diagnostics, consult Tesla service or use diagnostic tools.
Understanding battery degradation, maintenance, and optimization
*Based on typical usage patterns and Tesla warranty expectations
Very hot or cold climates accelerate degradation. Garage parking helps.
Frequent Supercharging and 100% charges can increase degradation.
High mileage and aggressive driving can affect battery longevity.
Newer Tesla models use improved battery chemistry for better longevity.
This calculator helps Tesla owners monitor their battery condition by comparing current range to original EPA specifications. Tesla batteries are designed for longevity, typically retaining over 80% capacity after 200,000 miles. Regular monitoring helps you understand your vehicle's performance and plan for the future.
Tesla batteries are designed to last 300,000-500,000 miles. Most retain over 80% capacity after 200,000 miles. Tesla warranties guarantee at least 70% capacity retention for 8 years or 100,000-150,000 miles depending on the model.
This provides a good estimate based on EPA range ratings, but actual battery health can vary based on charging habits, climate, driving patterns, and other factors. For precise diagnostics, consult Tesla service or use professional diagnostic tools.
Key factors include temperature extremes, frequent fast charging, charging to 100% regularly, letting battery drop to very low levels, high mileage, and aggressive driving. Tesla's battery management system helps minimize degradation automatically.
Not necessarily. Battery degradation is normal and expected. Most Tesla batteries show 5-10% degradation in the first few years, then stabilize. Only be concerned if degradation is rapid or below warranty thresholds (70% within 8 years).
While you can't reverse degradation, you can slow it down with proper charging habits: charge to 80% daily, avoid frequent Supercharging, don't let battery sit at very low or high charge levels, and keep the car in moderate temperatures when possible.
