When my SUV battery died it would not even operate the radio. I was able to jump it and get home but it wouldn't hold a charge after that. With a normal car battery I don't know that you have to go that low, however, to do damage. Deep cycle batteries, like I use for the trolling motor on my boat, are made to be pretty completely discharged. Car batteries are not. Normal use doesn't take them close to fully discharged.
