Battery replacements are generally about as frequent as getting a new transmission or engine. They’re rare, expensive, but if you want to pick something up on the used or remanufactured market it’s much cheaper. Supposedly the average battery will outlast the life of the car. My EV is only a year old, so I’ll have to get back to you on that, but the number I’ve heard is 10% degradation in 10 years.
