Electric cars don’t normally need a battery replacement during the car’s lifetime. If the battery needs to be replaced, the car has usually already been running longer than most ICE cars ever would.

But of course the fact remains, that there is currently a lot of demand for cheap EVs and little supply. The Chinese are gearing up to eat up that part of the market.
