Cool, now what happens to the battery/car after 7 years when you're trying to buy a new one? What's the battery range at year 7 and the value of the vehicle at that time?

From Caterpillar's website the 994H has a 1577 HP engine and can lift 35 tons (77,000 lbs) at once.

1577 HP consumes 85 gal/hr at 100% throttle, but it's not expected to consistently operate at full throttle & rated load (more likely 40-70% of each, I will use 60%) pic.twitter.com/vaL2OWbsll

The CAT 994h holds 1013 gal of diesel fuel. A nominal 60 gal/hr consumption rate will permit 16.9 hrs of operation, in which it will lift enough bauxite for 2,129 Tesla batteries. pic.twitter.com/O0i8vyzsa1

"Yeah but what about nickel?"
An 85 kWh battery contains about 90 kg of nickel, which is present at ~2% in the mineral laterite. So we need to scoop 90/0.02/1000= 4.5 tons of laterite (about the same as aluminum). So let's double our previous 12 lbs CO₂ to 24 lbs. pic.twitter.com/DzIz1S4oQd

(Note: this is not the total CO₂ emissions to manufacture a battery back, just those of the CAT 994h in the OP)

It is a common tactic in climate debates: express numbers like 500,000 lbs, 100 gigatons, 50 hiroshima bombs per second, etc to amplify minor effects. pic.twitter.com/CDfnGt5PmK
