Battery replacement also seems like a huge sustaining capital cost that never gets figured in when looking at the costs. What is the lifespan? Maybe a few years if you are lucky?

They tried the battery swap route. Both they and the public weren't huge fans. I wouldn't be terribly surprised if they don't do it for the Semi though. A lease agreement on the batteries could bring down the initial investment for buyers and reduce their unfounded anxiety on battery life.
Tesloop is operating a Model S with over 300,000 miles on it so far in just 2 yrs(?). School has over 90% capacity.
Tesla has brought in the world's leading battery excluded Jeff Dahn to try and help achieve some improvements.
One of the goals was you double the battery life. I think it was intended to be a 5 year protect. I think they double the expected battery life in a few months.
The completely arbitrary of 10 years is been assigned to the lifespan of the battery packso the soonest, we can infer that teslas battery packs may live above 80% capacity for I'll to 20 years.
In 10-20 yrs, the cost of knew batteries should be negligible compared with the savings in other maintenance and fuel savings.
