I spoke with a few mechanics... the most likely "battery draining" problem comes from a bad starter... stop by autozone,..etc.. they can check it for free... !
With the battery fully charged, you need to check the alternator, but first make sure all of the battery connections are clean , and tight,, with a multimeter, set the meter to DC volts,, place the red lead on the positive battery post, and the black one on the negative post, with the car running, you should get a reading of no less than 13.5 volts, if not you have a bad alternator,, if the reading you get is between the 13.5 and 14.5 volts your alt is fine, and you have something else draining your battery ., but keep in mind that if the cables were in bad shape , the alternator couldn't supply the power back to the battery with the loss it had while starting the car , here is a good link to see how to check the cars electrical system

I have a 99 sebring convertible LXI... I thought my battery was bad ...change it out twice to be sure.... if the car sits for 3 days the battery is completely dead... The second time I changed the battery I had the manager at the local auto zone put the meter to the alternator, etc..he said the altenator was good... charging... the cables to the battery all look good... I put new battery connectors on the Battery... Now I notice this is a big problem w seberings... what's going on? Chrysler should have a recall ... short or a faulty fuse connections??? Help in NC James
the only way to see whats draining the battery is to hook up a meter to the battery, and one by one ( I know this is very time consuming ) pull the fuses, if when you hook up the meter,, the battery shows a reduction in volts,, then the electrical in the car has draw , a radio or clock, draws very little , once you get to a fuse that stops the draw, that the circuit you have to check,
