You may want to review the thread about the same subject that I started a couple of days ago. In it I have some suggestions to prevent dead batteries (BatteryBrain)

Buy a CTEK 3300 Smart Battery maintainer and hook the eyelets onto the small battery terminal screw posts. Buy the CTEK Comfort Extension, and be sure to plug in the cord to the maintainer every time it sits idle. Be sure to lock the car even if parked inside the garage to make sure computer system in the car shuts down all electical modules. Most Jaguar owners are using this brand.
Here's the link to buy at Amazon.com......

By installing the CTEK 3300 it will end allot of frustration.

He has a new battery, mine is two years old. So, likely not a battery problem but, something hangs up in the electrical system and fails to shut off the current draws upon exiting the car. As I posted in my thread, upon shutdown there were several steps as the current gradually kept dropping from about 11 Amps all the way to 0.04 Amps, which is normal. If the process of dropping hangs at one point that would be the problem. In my case it hung for quite a while at 1.4 Amps which would account for a 3 days (100 Amph/hour) drawdown to complete failure.
After charging it, looks like my battery is OK and right now it is sitting with a normal discharge of 0.04 Amps. The best would be to install an event recorder that keeps track of time/current/voltage history. I used to have access to those at work but, no longer since I am officially retired.

Hopefully two problems solved. I had the dealer update the ECU on my XKR today. He said the software was still the original 2010 version which had that particular issue with battery drain due to the MOST bus not shutting down properly. I will be monitoring the battery for voltage for a while without any trickle charge.
