Re: The fuel tank in my car doesn't shrink each time I refill it.
EV batteries can also be overhauled. The batteries are made of many cells (90 in my 29kwh battery). When battery 'degrades' it’s usually down to one or two cells which can be removed and replaced. No need to replace entire battery. If too many cells degraded then the battery can still have value by using cells in power walls, standby power stores etc.
