Battery drain

Battery drain
I have a 2009 LR LR2 with 83,000 miles. I'm very happy with the truck but while I was away (3 days) I came home to a very dead battery. All accessories were off, nothing in auto mode with the security on. I had to use the manual method to get in, pop the hood and charge the battery. After an hour the truck started and everything is back to normal. As a daily driver all is good but that is not always the case. Any ideas on a source of the drain? I don't have navigation but it is set up for blue tooth, no codes showing up either. Software issue? HELP!
Thanks Bob

Following is an excerpt from a TSB that might apply to you. The solution requires software configuration by a Land Rover dealer.
Electrical - Battery Low/Dead For No Apparent Reason
TSB No: LTB00391 (ISSUE 1)
14 JULY 2011
SECTION: 415
FLAT BATTERY
AFFECTED VEHICLE RANGE:
LR2 (LF) w/Navigation only VIN: 8H000212 - Onwards
Model Year: 2008 – Onwards
CONDITION SUMMARY:
Situation:
The vehicle's battery may be flat, for no apparent reason, after the vehicle is parked overnight or similar period of non-use. This may be caused by the Infotainment Control Module not shutting down correctly if the following conditions occurred at the time of ignition OFF and exiting the vehicle:
1. Customer viewing the Navigation system map; and
2. Customer engaged in an active Bluetooth(R) telephone call.
If both of these conditions are encountered, a quiescent draw of approximately 1.5 amps on the battery may be induced, leading to the flat battery situation.
Action:
In the event of a customer concern of the above and after ensuring proper electrical system checks have been carried out as referenced in the Land Rover Battery Care Manual, refer to the Repair Procedure outlined below to update the Infotainment Control Module software.

All good for now
I took the LR2 into the local Land Rover dealer for things to get checked out. All systems are operating as designed with a new Land Rover battery. The battery that I had bought 6 months ago couldn't cut it. Sounds too simple, I've never had a battery go bad in 6 months..........anything is possible!?! All good for now. I have a trip coming up next month.............hope it starts!
