Response to EV battery questions

I just ordered my Equinox EV a few weeks back and I’m excitedly waiting. I’ve told a few people and the general response is “Isn’t expensive to replace the battery? Have fun with that!” I try to educate, but I’m still learning myself. What do you all say to this comment? I want an amazing answer that will make people actually look into EV’s and not believe all the negative propaganda. TIA!
