TESLA RELEASES NEW BATTERY HEALTH TEST! MY 2019 MODEL 3 LOST THIS MUCH CAPACITY IN 150,000 MILES

EV Channels Review

This video provides an in-depth look at the battery health of a 2019 Tesla Model 3 Performance after 150,000 miles, utilizing Tesla's new user-accessible battery health test. The reviewer highlights that while capacity loss is inevitable, his specific vehicle, equipped with an early Panasonic NMC pack, shows 81% remaining capacity. This figure, while noticeable and impacting range, is considered acceptable given the car's hard usage, including track days and extensive Supercharging. The reviewer contrasts this with other vehicles and emphasizes that battery degradation is often more pronounced in the initial stages and then plateaus. He offers practical advice on battery care, advocating for avoiding prolonged storage at high states of charge, especially in hot conditions, and suggests that consistent use of lower daily charge limits (around 50%) and avoiding extended periods at 100% are key to longevity. The video also touches upon the complexities of battery health measurement, warranty implications, and the evolving landscape of consumer-facing battery diagnostics.
