Have the charging system diagnosed by someone experienced, obviously the alternator is not charging the battery, on your car, I'm not sure if the regulator is integral to the alternator, or maybe a fusible link is burned out. Is it a new battery? 20 mins sounds like an old one, new should last at least 2 hrs with no accessories running, that's what's known as reserve capacity, usually expressed in minutes on the battery label, in case the alt dies on the road, at least car can be driven possibly to a safe location, lights, ac, will decharge it quickly.
