Just remember the charge discharge cycle cost around 5 cent per kWh in wear on the battery.
Is that until the battery stops working or till the 10,000 cycles 10 year guarantee?
Because there would still be life in it after that
It's the estimated average lifespan of a newish Lithium battery, but you are right that the "lifespan" is often defined as 75% remaining, so there should be life in the battery after that.
The newer sodium batteries should have way better lifespan, but I'm not sure if those are available yet.
