If it's still happening you'll need to check for parasitic draw.
Read something like this:
How to Find a Parasitic Battery Drain | eHow.com
Usually it's a result of what was last installed. Or something failed and the instrument cluster isn't going to sleep.
With Jeep not running, Install an ammeter with a shunt, turn on lights, radio - shut all off an you should seecurrent draw on the meter drop to .01 amps within a minute or so. If it doesn't start pulling fuses to seewhat circuit is causing it. Since there are fewer circuits with a TIPM these days - hopefully you can find that it's something you installed - or a warranty item.
