Didn't shut the door all the way and apparently ran the battery down It sat in the driveway from Sunday morning to Monday evening with the dome light on, which I didn't notice. Anyway....it started after jumping it from my dad's truck, but after running for about 30 minutes, I turned it off and it wouldn't start back up. Hooked it up to a charger and let it sit there all night. It is now the late-afternoon of the next day, the charger reads 14, and it still won't start. Is this usual? Battery is a DieHard, and I've only had the car for four years without replacing it (didn't need too). Did I ruin the battery, or is it the alternator? I did check the water and it has plenty. I don't know how long this battery has been in the car, but it's always started without problems. Thanks for any ideas.
