Tesla Model 3: Maintaining Battery Health and Minimizing Degradation


As the popularity of electric vehicles (EVs) continues to rise, it’s important for EV owners to understand how to maintain the health and longevity of their vehicle’s battery. The Tesla Model 3, equipped with a lithium iron phosphate (LFP) battery, is known for its cost-effectiveness and longer charge cycle. In this article, we will explore the best practices for preserving the battery health of the Tesla Model 3 and minimizing degradation over time.

Understanding LFP Batteries

LFP batteries, such as the one used in the Tesla Model 3, offer several advantages over other battery types. They are more affordable and have a longer charge cycle, making them ideal for entry-level EV models. Additionally, LFP batteries are considered more ethical as they do not use conflict minerals like cobalt, which have raised ethical concerns in recent years.

Factors Affecting Battery Degradation

Several factors can impact the long-term range and battery health of your Tesla Model 3. While battery age and the number of miles driven play a role, other factors such as driving style, climate, maintenance, and charging patterns are equally important. Understanding these factors can help you take the necessary steps to minimize battery degradation.

Charging to 100% vs. 80%

One commonly debated topic among Tesla Model 3 owners is whether it is better to charge the battery to 100% or limit it to 80% regularly. Tesla recommends fully charging the LFP battery to 100% at least once a week to minimize degradation. However, some owners have reported similar degradation levels when charging to 80% instead. It is essential to strike a balance between maximizing range and preserving battery health based on your specific driving patterns and needs.

Insights from Tesla Model 3 Owners

To gain further insights into battery health and degradation, we turned to the Tesla Model 3 owner community. Several owners shared their experiences and observations regarding battery degradation in various use cases. While most owners reported minimal degradation, some exceptions were noted.

One owner reported a 2.2% degradation in maximum range after driving over 20,000 miles with the Model 3 LFP. This owner charged the battery to 100% whenever possible and expressed satisfaction with the performance and battery retention. Another owner, however, experienced a higher degradation of nearly 4.8% over two years and 85,000 miles. It is important to note that individual experiences may vary, and other factors such as battery management system (BMS) calibration can influence the displayed range.

Battery Management System Calibration

The battery management system (BMS) plays a crucial role in monitoring and maintaining the health of the Tesla Model 3’s battery. Inaccurate BMS calibration can result in the displayed range not accurately reflecting the actual capacity. However, owners have reported that BMS calibration can be easily recalibrated by allowing the range to drop below 10% for an hour and then recharging to 100%. This process resets the system and provides a more accurate range estimation.

Tips for Maximizing Battery Range

Tesla Model 3 owners who have accumulated significant mileage on their vehicles have shared valuable tips for maximizing battery range and minimizing degradation. Here are some key takeaways:

  • Avoid frequent deep discharges: Deep discharges can put additional stress on the battery and accelerate degradation. Try to avoid letting the battery level drop below 20% regularly.
  • Optimize charging patterns: Charging regularly to 100% can help recalibrate the BMS and maintain battery health. However, if you do not require the maximum range for your daily needs, charging to 80% can help strike a balance between range and battery longevity.
  • Consider climate control settings: Extreme temperatures, both hot and cold, can impact battery performance and range. Preconditioning the vehicle while connected to a charger can help mitigate the impact of temperature on battery efficiency.
  • Maintain appropriate tire pressure: Proper tire inflation not only improves overall vehicle efficiency but also contributes to maximizing the battery range. Regularly check and maintain the recommended tire pressure for optimal performance.
  • Opt for regenerative braking: Utilizing regenerative braking can help extend the battery range by converting kinetic energy during deceleration into usable energy. Adjust the regenerative braking settings to suit your driving preferences and optimize energy recapture.


Preserving the battery health of your Tesla Model 3 is crucial for ensuring optimal performance and range over time. By following the best practices outlined in this article, such as charging patterns, BMS calibration, and optimizing driving habits, you can minimize battery degradation and enjoy the full potential of your electric vehicle. Remember that individual experiences may vary, and it is essential to adapt these practices to your specific driving patterns and needs.
