If I were to charge a Model Y battery, for how long would it keep its charge?
Owners of Teslas can anticipate at least 267 miles of range on a single charge.
CEO Elon Musk claims a single charge can power a Tesla for at least 267 miles.
The lifespan of the battery itself is estimated at 35 years. However, Tesla makes the batteries in the Model Y to last even longer.
For 8 years or 120,000 miles, whichever comes first, their battery warranty ensures against degradation of more than 70%.
Further, many Tesla Model Y owners claim their batteries last between 300,000 and 500,000 miles before they need to be replaced.
In other words, if you put 13,500 miles on your car every year, you'll be doing a lot of driving.
The lifespan of a Model Y battery is estimated to be 15–25 years.
