As in it's frequent. I'd estimate about as frequent as someone running out of charge in an EV nowadays.

(If you're in a hot climate, e.g. Arizona, and park your car outdoors, it literally can be every year or two.)

Apparently they're still marketed to commercial users, pricing in the $5k+ range. EV to EV charging, emerging on newer vehicles, would be the analog.
