Huh?
If 80A is harder on the battery, what does Supercharging do to it?
It is harder on the battery than 80A.
All of this is not rocket science. Charging creates heat, heat speeds up chemical reactions including degradation.
Yes, some have supercharged 500 times and have normal range degradation. But all things being equal, a battery will live longest at coldest temperature (above 40 or so). 80A charging will heat the battery more than 40A charging. Will it make a practical difference in the car's lifetime? - probably not.
Generally, if I only need 40 miles a night, it is just safer in multiple ways to charge at 40A (or even 30A). At some point, there is usually an efficiency hit at too low of an amperage so I would not really go lower.
