Well, I just called to see what's the latest, and I was told my car is ready to pick up. You think someone would be happy to call and tell me it's fixed? Apparently not.
I'm at work now and won't be able to get it until tomorrow...
Call me a pessimist but I didn't really like the resolution. They clean excessive paint off the grounds which was causing increased resistance. The car sat last night and this morning there was no low battery message.
I sure hope I don't go pick it up tomorrow morning to find the message returned. If it really is fixed, I'll be a happy camper.

Living in desert always a challenge for batteries, some last years some don't. Zero problem with Jag, more problems with strange looking Italian battery in Maserati. Jag can sit for a week and nothing different, Maser can be problem after 3 days, can drop to 60% and not start car!

Yes, mine too. They appear to be the same batteries in all F-Types since introduction.

I've gotten in the habit of testing the resting voltage before I start the engine, and it was reading 11.7--lowest I've seen since I got the plug-in voltmeter. It started fine, and shortly after pulling out, the reading shot up to the high 13's with spikes over 14v. It stayed in the 13s during my entire 30 mile commute.
As I previously reported, if it's been on the BT for 24hrs., the resting voltage is 12.7 and drops to between 12.2-.4v as I'm driving, and I only get spikes in the 13-14 range after driving for about 20 miles or more.
What seems to be different about this car is the battery mgmt system software is programmed to only put the alternator into action when the battery voltage falls to a certain level. The other weird thing is that the resting voltage of my motorcoach after charging is always above 13v. vs. always 12.7 on the Jag.
What these data seem to suggest is that the battery management system software does not allow the alternator to fully top off the battery as I'm used to in other vehicles.

I have a base F-Type, only upgrades are the "Premium + Vision Pack." 1200 miles on the odo now. I just got a ciggly plug-in voltmeter and checked two cars: Audi Q5, ignition on, reads 12.4-12.5 volts, on fast idle (2000 rpms) reads 13.2-13.3 volts. F-Type ignition on, reads 12.4-12.5 volts, on fast idle (2000 rpms) reads 12.8-12.9 volts. Jaguar has not been driven in 24 hours.
I have had no errors or warnings, car starts and runs perfectly. I will test the Jaguar on my next road trip to get more data. Guess I'd agree with Foosh on this one.

Well, I have the F-Type back home. Will post after I give it a few days of normal use and see if the solution of cleaning excessive paint from grounding strap did the trick...
Now, to highjack my own thread just a little... While I was at the dealer picking up my car, I wanted to get another quart of oil... The guy behind the counter brings out a quart of Castrol Edge 0w20... and proceeds to charge me $17. I politely tell him, this isn't the proper oil, I'm looking for the Castrol OE Professional (in the gold bottle)... He tells me, this is what the tech gave me and he said it's what we put in the F-Types for the 0w20 oil changes...
If I am not mistaken, the Castrol EDGE doesn't meet the Jaguar requirements for additives and whatnot... (per the owner's manual of course)

I'll have to look also. Don't like idea of anything I have to depend on to work to be Italian, clothes, leather, food sure. Machines....no. From experience as a Maserati owner, made by people that take 2 hour lunches with wine!

At least that is what Jaguar Harrisburg put in mine at last service/oil change

Normally 24 hours. Sometimes a bit less. Since most of my driving is short trips to the store I plug it in every week or two. In over a year I have never seen a low battery warning.

The F-Type has not sat for 48 hours (without using any BT) since I have been out of town. I just went to check on it, and there is NO low battery message...
Perhaps the ground was the issue for me.

As a quick follow up... One week later, normal driving, and no BT... I have experienced NO low battery messages since they cleaned the ground. Way too simple of a solution if you ask me, but I'm currently a happy camper!

The more I think about it, the more it this explanation makes sense. Intermittent grounds have stumped people for years. It's kind of refreshing to see an old-school problem being the simple solution on a modern car.
The issue may have been located where the ground strap bolts to the frame, which is painted before the bits and pieces are mounted. The paint just wasn't adequately removed at the attachment point.

The Castrol professional replacement oil is missing the A5/B5 spec, which is the high performance part of the string of letters on the label.
There is a motul specific oil that has all the correct alphabet soup on the label including the A5/B5 but I was not able to buy it in the US.
My solution is to change the oil every 7500 miles. I may order the motul specific oil from Europe off EBay.UK at some point. It is frustrating to not be able to get the correct oil, even at the dealer.

Due to a mix of bad weather and too much other things to do, my car sat for 14 days without being used now. Plugged the Ctek BT in earlier today and checked it after some 5 hours, and it showed a fully charged battery.

Since I've had mine back from the dealer after the fix, I drive the car every Fri, Sat, Sun, and it's garaged the rest of the week. I have not plugged the BT in, nor have I received any low battery messages.
Anyone having any issues, I would highly recommend checking the grounds, if you know where they all are and can find them. FWIW, my service invoice stated the ENGINE GROUNDING STRAP...

Ok...looks like I've been stung by the battery/charging issue. Just before I left on my 8 day journey, I was getting the low battery warning every morning. I even tried to keep the battery healthy with a 300ma battery tender. Couldn't keep up with whatever drain was occurring.
I took it in and they charged up the battery, confirmed it was strong and confirmed the charging system was working just fine. They suggested I had accidentally left something on (unlikely, but go along with that theory once). When I locked down the car for the trip, I made certain nothing was on.
Fast forward 8 days: won't unlock, no light, no sound, no nothing. DEAD!
Used the manual key to break in and open the hood so I could attach a battery charger. If the battery is good and the charging system is working, there must be one helluva parasitic drain somewhere.
