How to Check Tesla Battery Health in 4 Ways

Want to know how to check Tesla battery health to ensure that your EV continues to work longer and smoother? Read this guide to learn all about Tesla battery health.

About Tesla Battery Health

Right now, each of the four Tesla models has the most powerful and high-performance electric vehicle batteries. Like all electric vehicles, the lithium-ion battery of each Tesla model gradually reduces over time. The battery degradation is normal, and it gradually loses some of its power and range.

However, many factors affected Tesla’s battery health, including:

  • Improper charging
  • Battery age
  • Temperature
  • Depth of discharge
  • Recharge rate
  • Drive condition

That is why it is recommended to check your Tesla battery life to ensure optimal performance. The health of your Tesla battery is very important because it affects your vehicle’s performance, drive range, and resale rate.

When you check Tesla battery health, you see the estimated performance and remaining capacity of the battery as it ages. You can compare the current battery capacity with its original capacity to get insights into the extent of battery degradation and the health of your car.

How to Check Tesla Battery Health in 4 Ways

The regular valuation of your vehicle’s battery health is important. Whether you have the slick Tesla Model S, the family-friendly Tesla Model 3, the SUV Tesla Model X, or the versatile Tesla Model Y.

Here, we have shared 4 methods on how to check Tesla battery health.

1. Comparing the Current Range to Epa-Rated Range

Compare the current drive range that is displayed on the screen to the Epa-rated range to check the Tesla battery’s health. If you see a 5 percent or less reduction in range, it means it is normal degradation. But if the current range is remarkably lower than the Epa-rated range, it means that the capacity of the battery has reduced over time.

2. How to Check Tesla Battery Health in the App?

  • Open the Tesla app on your phone.
  • In the app’s menu, choose your vehicle option and then go to Upgrades.
  • Now tap on the battery option.
  • Here, you will see the battery health check in percentages.

3. See Battery Health in the Tesla Account

  • Log in to your Tesla account.
  • Go to the charging tab.
  • Here, you will see all the information about the battery, including total rated miles and loss of range since new.

4. Check the Number of Miles

Another way to check the Tesla battery health is to monitor the number of miles driven till your car needs another charge. Do this check every time you charge your vehicle, and then you will know the battery capacity and performance.

How to Know the Tesla Battery Health Results

So, you know how to check Tesla battery health, but do you know how to conclude the results and know whether your Tesla battery is still performing optimally or not?

Here, we have shared how to understand the results after checking the Tesla battery health.

Battery Capacity

The percentage of battery health indicates the remaining capacity of your Tesla battery. It shows how much of the original capacity the battery can still hold. However, if you see the lower percentage, it means the battery is degrading. Meanwhile, the higher percentage means that the battery performance is optimal.

Battery Range

The battery range provides your Tesla performance results. When you compare the current range of the battery to the rated range when the vehicle was new, you can calculate the percentage change in range to know the battery’s health. As mentioned above, if you see a 5 percent reduction in range, it means it is normal degradation. But if you get a percentage higher than 5, it means the battery is degrading.

Why is a Tesla Battery Health Check Important? Reasons

  1. The Tesla battery health check lets you keep track of the battery’s overall health. As the battery ages, the battery capacity reduces, and its ability to hold a charge reduces as well. That is why knowing the battery’s health can help you plan for battery replacement when required.
  2. The battery health check also shows you the insight data of your Tesla. When you are selling your car, a healthy battery is more valuable than a car with a battery that is close to the end of its life. So, checking the battery’s health can help you know the car’s value and negotiate a fair price when selling.
  3. The battery health check also helps you know how your driving habits affect the battery’s health. For instance, frequent use of power charging can reduce the battery capacity over time. So, if you are aware of this, then you can adjust your charging habits to extend your Tesla’s battery life.


In this post, we have shared how to check Tesla battery health in four different ways. Once you know the results of battery health, it lets you plan the battery replacement when required, see the car’s selling value, and learn about the factors that affect the battery life. So, it is recommended that you practice good habits to increase your Tesla battery life.
