The battery's "limited lifetime" is currently longer than the expected lifespan of the car. The vast majority of EV batteries are still in "first use" and that is including more than a decade of Nissan Leafs (the model with the worst issues of battery "degradation" known to the used market). People are still driving the first and only battery of the car into a car's second decade (and likely will into its third, but it is too soon to tell). Statistically speaking, an EV is more likely to be totaled entirely in an accident than to have its battery replaced.
