Tesla’s 850,000 mile battery

Home / Batteries / Tesla’s 850,000 mile battery

If the cars being tracked in the below analysis were to degrade in a straight line from this chart, somewhere near 850,000 miles of driving is where the cars would hit 80% of the original mileage. I’m pretty sure I’ve not driven that many miles in the twenty years I’ve been behind a steering wheel. Every single analysis you’ve heard on the lifetime of energy storage is wrong.
