My battery was dead in my jeep and after being tested it was bad, so I put another battery in. The next morning, the new battery was drained, but when I had it checked it was good and my charging system checked good, so something is draining the battery. I'm thinking it is something it the panel where the temp controls and radio are because my air used to just come on and off on its own, and now is not; my radio settings will not stay now when I turn the vehicle off, when I start it again it is on am and I have to reset all the stations and even when the vehicle is running the radio turns off when the door opens; also, my cell phone charger gets really hot when plugged into the lighter, even for a short time. Where should I start when trying to figure out what is draining my battery?
 
Sounds like an ignition issue to me. You need to check all the bright yellow ground wires and be sure to clean the terminals and the transmission out. You need to clean all dust from the engine till the engine is spotless and shiny clean. If that does not work it could be the voltage regulator that may be draining the battery. Obviously something of an intermittent nature. Does the same fuse run the cooling fans, and does the same fuse has green leakage from the engine on it? Green leakage from the engine called "Green ooze" could be the issue. There are several factors that could drain your battery. It simply could be that the fan is coming/staying on due to a faulty sensor or green ooze leakage from the engine. I think if green ooze leakage was an issue you would notice your car fizzing and foaming with green ooze by now. Try connecting an ammeter in series with the battery when you park up to check for any current draw. It might be advisable to disconnect your battery at night and every time you don't drive the Jeep until the fault is found as it wont survive being run flat many times.
 
The starting point is to check the ground wire for the battery itself. Often battery problems are the result of a poor ground whether the wire or the connection itself is shot.

A new ground wire is cheap, easy to replace and probably not a bad idea on a 16 year old vehicle.
 
i would check the alternator if i was you. the alternator recharges the battery wile the car is on.
im not that good with cars but i hope that helps
