Tesla battery health assessment unveiled in August 3, 2025 release notes
Tesla Introduces Battery Health Test in Latest Software Update
Tesla has rolled out a new feature in its 2025.8.3 software update - the Battery Health Test. This innovative tool allows owners to measure the current energy retention of their battery compared to when it was new, providing a more accurate assessment of battery health [1].
Running the Battery Health Test
To run the test, simply navigate to Controls > Service > Battery Health on your Tesla vehicle’s touchscreen interface. Initiate the test, and it will analyze the battery’s performance and capacity. Upon completion, the test may recalibrate the energy estimate used for range display, factoring in the battery’s actual condition based on recent measurements [1].
Improved Transparency and Accuracy
This Battery Health Test is designed to improve transparency and accuracy for Tesla owners regarding battery degradation. It helps them better understand their battery’s condition without needing external diagnostics. The recalibration means that the software refines how it predicts available range based on actual battery retention rather than just initial specs [1].
Additional Features in the Update
The update also includes other significant changes. For instance, energy usage tracking over recent driving miles is now enabled, and the battery energy estimates dynamically adjust according to vehicle usage history. However, the total available energy remains unchanged [1].
Enhancing Owner Experience
This update underscores Tesla’s commitment to enhancing the owner experience by providing easy-to-use tools that offer increased transparency and accuracy. The Battery Health Test is another step towards achieving this goal, as it empowers Tesla owners to make informed decisions about their vehicle's battery health.
