MODEL 3 Y BATTERY HEALTH TEST IN TESLA SERVICE MODE 2023 AUSTRALIA

EV Channels Review

This video details how to perform a battery health test on a Tesla Model 3 Performance (2019) using the vehicle's service mode in Australia. The reviewer, Tesla Tom, successfully executed the test, which took approximately 19 hours, yielding a battery health of 91%. He notes that the process requires software version 2023.6.8 and can be lengthy, potentially up to 24 hours, with specific conditions like being plugged into a 6kW AC charger and the battery state of charge being below 50% initially. Tom also compares the service mode result with the 'Scan my Tesla' app, finding them to be comparable after recalibration. He highlights that proper battery calibration (draining to near zero and charging to 100%) is crucial for accurate readings, potentially showing a 2-3% difference compared to an uncalibrated battery. The reviewer concludes that 91% health after 3.5 years and 59,000 km is acceptable, with a degradation of 9%. He suggests 'Scan my Tesla' as a quicker alternative if the car is needed daily, while acknowledging its own margin of error.
