Well ya, I got years left still.

But at 8 years it’s resale value will be much higher than at 8 years with a 15-20k battery replacement if it dies.

There’s a cost/risk to consider there, it just working isn’t a financially sound decision on its own

Edit: also by the time 8 years is up,getting a 1 year old car to eat that initial depreciation will be easier.
