Nine-volt battery positive and negative poles

Years ago a friend of mine had a Triumph TR3 with a dead battery. He got someone to boost it but they connected the cables backwards. He did not know this, drove about 50 miles and charged up the battery backwards. Apparently this is possible but once the battery polarity is reversed you can''t change it back without ruining it.
