Done. But when my battery needs to be replaced (not expected before 2022), I don't want to have one with at least 70% capacity compared to the original one. That would result in 60-70 km under cold conditions and is not an option. The idea of getting a second hand battery replacement is not bad, but it should use battery cells that are "up to date".

Now I have 18,7 kWh nominal capacity. In 2022 a used battery replacement pack should provide around 22 kWh of usuable energy. I will not accept a battery replacement pack with 8 year old battery cells and only 13 kWh capacity left.

Dear PowerTower

Many thanks for you feedback!
Indeed, only "up to date" cells get into the discussion for EV use.
I agree with you that 70% is not really an option...if its cost is extremely low, one who makes a very limited use of the car could be interested but this is clearly not a case we should focus on.
