How to Check Tesla Battery Health: A Comprehensive Guide

If you own a Tesla Model 3 and want to perform a battery health test, accessing the service mode is essential. In this guide, we’ll walk you through the steps needed to access the service mode and conduct a battery health test for your Tesla Model 3.

To initiate the service mode, follow these steps:

  1. Tap the car icon located at the bottom left of the screen.
  2. Proceed to the “Service” section and hold down the car icon for the Model 3.
  3. When prompted for the access code, enter “service” and press enter.
  4. Select “enable” to enter the service mode.

Upon enabling the service mode, your car will automatically deactivate the AC, indicated by a red line around the screen. Next, navigate to the “Battery” section and click on “High Voltage”. You will then be able to view your battery health percentage.

When running the battery health test, ensure the charge is below 50%, the vehicle is plugged into a level-two charger, and be prepared for potential noise and heat generation during the discharge process.

After completing the test, check your Tesla app to verify if the car is still in service mode. The results of the battery health test should now be accessible.

Upon completing the test, it’s advisable not to leave your Tesla at 100% state of charge, unless equipped with the new LFP battery. It’s essential to discharge the battery to a lower percentage before extended periods of inactivity.

It’s important to cross-verify the results obtained from the battery health test with other apps like Tessie. Additionally, it’s recommended to avoid leaving the car at full charge post-test.
