What could be draining a fully charged battery in less than 24 hours on a 2009 Hundyai Eleantra? Battery less than 6 months old, alternator and starter both passed testing.
Battery less than 6 mos old draining from a full charge in less than 24hours. Alternator and starter tested at Oreillys on full battery. Both passed all categories and battery tested good also. What could be the problem?
