Headlights Left On, Drained Battery

I had a friend come over to jump the battery. He left his car on for approx 5 minutes before I started my car which was successful and we then left both cars running and connected for an additional 5-10 minutes.

Should I check if there was any damage to the battery or alternator? I made sure to take breaks and limit drives to 15-20 minutes so the alternator doesn't get too hot. How long does the battery take to fully charge?
