Consumer car batteries charge 20->80% in under a half hour these days, and are warranted for a minimum of 8 years.

30 minutes seems slow until you realize that you hardly ever need to charge the car away from home. I do not miss going to the gas station!

I’d guess the mechanisms needed to swap the battery would be more maintenance than they are worth.

I guess for delivery vans, which drive during peak solar production, doubling the number of batteries so you can charge during the day might make sense.
