Well in current terms it means number of cycles to 80% capacity.
So about 3500 cycles to 80% or something like that.

I think there are several points not being said - or asked.
1. What does "last" mean? 99% capacity, 90%, 70%.
2. What is the comparison between +10% cost for this supposed product
and using only 70% capacity of the current battery in your car -
meaning
you overpaid by 30%.
3. How much more value is left in the battery after 300K miles of use -
for repurposing as grid storge, e.g.
