I doubt it. Most electric car manufacturers offer a 8-10 full battery warranty with their vehicles. I don’t think an extra 4-5 years is something they would risk consumer satisfaction for.
At the price of cars they have to last. If cars only lasted 1 year then they would sell a lot more cars, but they would be all bare bones and lower overall profit - many buyers would be willing to save $500 by not getting the heater option since they have to pay the entire cost of the car every year. Because the average car is 12 years old car manufactures can sell the trade in value of the car - they know someone else will buy the car when it is 3 years old and so the real cost of a brand new car is 1/3 to 1/2 the actually price.
We have been trained to think of cell phones as semi-disposable. If people had to replace their car's $10k battery as often as they replace their phone they would be dead in the water.
You can replace the battery, it’s just that they want to save as much space as possible for smaller and smaller phones. Also having to take it in to replace the battery means you’ll probably think about buying a new phone instead which is what you’re implying.
