I replaced battery in my 2000 Concorde in 2005 and 2007 and still seems to have battery drain for no apparent reason. Randomly doesn't start but does start up after using battery charger. I had driven it 25 miles to resturant last time it happened and started right up later and drove 15 miles when it stuttered momentarily but continued another 10 miles before a stutter then minute later shut down completely. Had headlights when trued. Dashboard lit up normal for turning key,but only a single click sound Repeated 3 times.........same thing dash lit up, and only one click. Still had headlights. when tried.
Next time it happened it, had sat in garage over night, Used charger and it started right up. Didn't drive. Next morning had to charge again, then it started right up. It has run fine again since Thanksgiving day.
It's making me paranoid to drive it. It's a great car otherwise.

The most common cause of this by far is lights left on by defective switchs, these include the map lights in the visors, the glove box light due to a defective switch, the trunk light and the hood light if equipped, check it at night and look for a faint glow, the other much less common cause is the alternator has a defective diode and allows a small current to pass to ground drawing the battery down..
why did u give me a thanks for trying rating??, your comment indicated the info was useful

I printed your comment on possibilty of automatic light switches not going off or alternator diode problem to my Chrysler dealer and after keeping it a week without problem occuring, they don't feel it is either problem but said to have it towed in if it occurs so they can check it out while the problem is actively happening. They feel there is a battery drain from some thing, but haven't found it. I thanked you because it may have helped rule out those things.
It has started up fine this weekend but that is the history of it's behaviour.
