2010 XF not starting. Battery issue?

I tried starting my 2010 XF and all I got was a single click sound. All of my interior/exterior lights and radio worked fine but I could not get the vehicle to start. No lights were left on the night before. I attempted to jump it but still could not get it started. The car seemed to get a burst of energy and wanted to start but just would not turn over. Shortly after trying multiple attempts the car went crazy, flickering all the exterior lights and repeatedly sounding the horn as if it were alarming. The lights and horn deteriorated moments later almost being unnoticeable. Ultimately I ended up disconnecting the battery.
Does this sound like just a dead battery or something more? I did take the vehicle in last year for a "system upgrade" recall due to this vehicle model draining the battery when it's off for no apparent reason. Do Jag battery's only last 2 years? Any thoughts?
Thanks!

Should be just the battery. As for the life of a battery there are too many factors involved in how long it will last. Some last for many years while others only a few. When jumping the car using the instructions specified in the owners manual it would have to charge the dead or near dead battery in this case to an acceptable prior to attempting a start. The flashing/cycling of all the gauges etc should be the voltage was just at the point of not being able to support the basic system requirements. Hope this helps. Good luck

When I had the cables initially hooked up it cranked slightly (more than a click) but nowhere near wanting to turn over. I ended up having to call a tow the next day. We were able to eventually get it jumped but the gauges continued to go wacky. The tow guy then told me he’s towed a handful of newer Jags for what appears to be a battery issue.
Thankfully the tow guy was extra careful while hooking it up and loading it on the truck but the car did throw off some frightening noises.

One of the jag techs on here said the electronics really load down the batteries on newer cars (not just the XF). It's possible the battery was on it's way out before you had that update and it got progressively worse until now when it gave out. Someone said the batteries are covered under the normal warranty so the dealer should replace it if your car is still under warranty.

Looking at it in a different light, the "system upgrade" they did initially would not take. They told me the computer froze several times halfway through the install. I had to make multiple appointments, each lasting a full day until it finally took. I'm not sure if that had something to do with it, but then again, I do only drive the XF about 2-3 times a week totaling around 3 hours worth of drive time.

If the engine won't turn over with a jump from a known good battery then your problem is with the starter or its wiring. The alternator is never relevant to a fail to start except if it is the cause of the dead battery. A failed alternator will not prevent the engine from starting and running.

Ultimately they only had to replace the bad battery. There was no alternator or computer issue. Apparently they did not hook the battery up right when they did their charge test but eventually they figured that out. Everything seems fine now thankfully.

The state of the original battery is not affected by jumping. Any jumper cables are connected in parallel to the car battery and no current passes through the dead battery. Any charging happening would feed both the dead battery and the jumper battery simultaneously. The jumper battery cannot charge the car battery.

Not quite true. Connecting a fully charged jumper battery to a discharged battery is the same as connecting a battery charger to the discharged battery. The jumper battery will begin to charge the dead battery just like a battery charger. However, unless the charging vehicle is running, the two batteries will eventually end up in some equal state of discharge.
But, whatever, the point is that the state of the dead battery is irrelevant if you are jump starting the engine. If the engine won't jump start it isn't the battery. If it is the battery it doesn't matter how dead it is, the jumper battery will start the engine.
Finally, correct jump starting involves using the boosting car while the engine is running. The boosting car is charging both batteries simultaneously and, technically both batteries contribute current, if current is available and then only if the alternator on the booster car cannot deliver enough surplus current to start the dead car.

Unfortunately, I’m continuing to experience the same issue with my XF after all this time. It’s seen the service center more than once and continues to sit dead in my garage. I made another appointment to have it serviced but this time I made an extra call to the manufacture. The manufacture informed me a "case" will be opened regarding my issue and that they will be connecting with my service center while it's being serviced. Additionally, they made mentioned about possibly buying back the title which made me nervous. Has anyone had problems with their Jaguar that initiated this type of response?
