Batteries don’t have to be recycled every 8-10 years, nowhere near. If you keep them within temperature and leave a safety margin they’ll outlast the car. There’s already plenty of data for Tesla batteries lasting hundreds of thousands of miles without significant degradation. Look after Lithium Ion batteries and they’re good for 1500 cycles, that’s 300k miles for a 200 mile car, 450k miles for a 300 mile car.

These aren't average cars, they're delivery vehicles meant to be driving rather a lot. Just ball parking here, but 100 miles per day, 6 days a week, 50 weeks a year is 300k miles in 10 years. 8-10 years doesn't seem that off the mark given your numbers.
In the special case of delivery vehicles that applies. But the high mileage also means a phenomenal reduction in carbon emissions and pollution over those 300k miles.
