Understanding Tesla’s Battery Health and Capacity
Before running a battery test on your Tesla, it’s essential to understand the basics of Tesla’s battery health and capacity. Tesla’s battery management system is designed to optimize battery performance, longevity, and safety. Here’s what you need to know:
Battery Health
Tesla’s battery health is measured in percentage, with 100% indicating a brand-new battery. As the battery ages, its capacity to hold a charge will decrease, and its health will degrade. However, Tesla’s battery management system is designed to slow down this degradation process.
A healthy Tesla battery typically has a capacity of around 90% to 95% after 100,000 miles. However, this can vary depending on factors such as driving habits, climate, and charging patterns.
Battery Capacity
Tesla’s battery capacity is measured in watt-hours (Wh). The capacity of a Tesla battery determines how far the vehicle can travel on a single charge. The capacity of a Tesla battery can range from 50 kWh to over 100 kWh, depending on the model and year.
For example, the Tesla Model 3 Long Range has a battery capacity of 75 kWh, while the Tesla Model S Long Range has a battery capacity of 100 kWh.
Preparing for a Battery Test
Before running a battery test on your Tesla, make sure you’re prepared by following these steps:
Charge Your Battery
Charge your Tesla’s battery to 100% capacity. This will ensure that the test results are accurate and not affected by a partially charged battery.
Update Your Software
Make sure your Tesla’s software is up to date. This will ensure that you have access to the latest features and diagnostic tools.
Choose a Testing Method
There are two methods to run a battery test on your Tesla: the built-in battery test feature and third-party testing tools. The built-in feature is available on newer Tesla models, while third-party tools can be used on older models.
The built-in battery test feature provides a quick and easy way to test your battery’s health and capacity. However, it may not provide as detailed information as third-party testing tools.
Running a Battery Test Using the Built-in Feature
If your Tesla has the built-in battery test feature, follow these steps to run a test:
Access the Diagnostic Menu
To access the diagnostic menu, go to your Tesla’s touchscreen display and navigate to “Settings” > “Service” > “Diagnostic.”
Select the Battery Test Option
In the diagnostic menu, select the “Battery” option and then choose “Run Test.”
Wait for the Test Results
The battery test will take a few minutes to complete. Once the test is finished, you’ll see the results on the touchscreen display.
The test results will show your battery’s health and capacity as a percentage. You’ll also see a graph showing your battery’s charging and discharging patterns.
Running a Battery Test Using Third-Party Tools
If your Tesla doesn’t have the built-in battery test feature, you can use third-party testing tools to run a battery test. These tools can provide more detailed information about your battery’s health and capacity.
Choose a Testing Tool
There are several third-party testing tools available, including ScanGauge, TeslaScan, and EV-CAN. Choose a tool that’s compatible with your Tesla’s model and year.
Connect the Testing Tool

Understanding Your Tesla Battery’s Health
Before diving into the specifics of running a battery test, it’s crucial to understand what factors contribute to your Tesla’s battery health and how it’s measured. The battery’s state of health (SOH) reflects its ability to hold and deliver charge compared to when it was new. Several factors influence SOH, including:
Factors Affecting Tesla Battery Health
- Temperature: Extreme temperatures, both hot and cold, can negatively impact battery performance and longevity.
- Charging Habits: Frequently charging to 100% or deeply discharging the battery can accelerate degradation.
- Driving Style: Aggressive acceleration and braking put more stress on the battery.
- Age: Like all batteries, Tesla batteries naturally degrade over time.
Tesla monitors battery health continuously and provides insights through the touchscreen display. You can access battery information, including SOH, range, and charging rate, under the “Vehicle” tab.
Measuring Battery Health: SOH
The SOH is expressed as a percentage, representing the remaining capacity compared to the battery’s original capacity. For example, an SOH of 85% means the battery can currently store 85% of its original charge. Tesla aims for an SOH of at least 70% after eight years of use, but factors like driving habits and charging practices can influence the actual lifespan.
Running a Battery Test on Your Tesla
While Tesla doesn’t offer a dedicated “battery test” function in the same way some traditional car manufacturers do, there are several ways to assess your battery’s health:
1. Reviewing Battery Data in the Tesla App or Touchscreen
The Tesla app and touchscreen provide comprehensive battery information. Pay attention to the following:
- State of Health (SOH): This percentage reflects the battery’s remaining capacity.
- Estimated Range: This shows the estimated driving range based on current battery charge and driving conditions.
- Battery Temperature: Ideal operating temperature ranges are typically displayed.
Monitoring these metrics over time can help you identify potential issues or trends in your battery’s performance.
2. Conducting a Range Test
This involves driving your Tesla on a predetermined route under consistent conditions and observing the actual range achieved. Compare this range to the estimated range displayed on the touchscreen. A significant discrepancy might indicate a battery issue.
3. Utilizing Tesla’s “Battery Preheat” Feature
In cold weather, Tesla recommends using the “Battery Preheat” feature before driving. This warms up the battery, improving its performance and range. Observe how quickly the battery preheats and its impact on range. Slow preheating or reduced range could signal a problem.
Interpreting Battery Test Results
Interpreting battery test results requires careful analysis. A slight deviation from expected range or SOH might be within normal limits, especially considering factors like temperature and driving conditions. However, consistent or significant deviations warrant further investigation.
If you suspect a battery issue, it’s essential to contact Tesla Service for a professional diagnosis and potential repair or replacement. They have specialized tools and expertise to assess battery health accurately and provide appropriate solutions.
