[MSCW list] Battery dead after leaving headlights on for 20-30 minutes on 2010 Mazda3 S 5-Door Sport

The car was bought in September 2009, so it is 4 years old. ?After a jump start and driving it around, the battery charged up and the car starts. ?I've been doing a little bit of internet research on battery drain problems in 2010 Mazdas and am of the opinion that the stock, non-maintenance-free battery in this car leaves something to be desired. ?Some people have left an interior light on somewhere for a couple of days, and that also kills the battery.

Here it's recommended to replace the battery every 4 years, which I'm going to do: ?http://www.carcarekiosk.com/video/2010_Mazda_3_i_2.0L_4_Cyl./battery/replace_battery
