Actually this is probably incorrect, at least for vehicles. Most people don’t wait for their engine to die before getting a new car. Having a vehicle battery that can maintain its storage capacity would be a huge benefit for the adoption of EVs, as well as for the used and new car markets. Auto manufacturers make more on a battery in a new car than in having to sell one to replace a depleted battery in an old car. The residual value of batteries from older vehicles would be a benefit to the used car and salvage markets. Your car frame might be totaled but your battery might be reusable or recyclable.
