Don't forget he is dealing with this issue in Russia not the states, VERY different environment.
In the end it was likely solely a battery issue, one that recharging it probably won't ultimately help IF the battery ever got down to a low level of discharge as once it gets there it'll never be the same. IF it was low, then stomping on the brake won't help you in fact it'll make it tougher even when the battery voltage level raises slightly as the master cylinder will be more pressurized resisting your efforts. It's possible it was a brake sensor but cheaper and likely "insurance" to simply replace the battery (AND fully charge it with a god maintainer) even if precautionary. Sounds like your car is working now hopefully you'll not see this gremlin again. Not sure about which battery sorry no help there

Go to the search box at the top right hand side of this thread and enter Battery specifications. See if that will provide you with what you need. I just checked the owners handbook and unfortunately there is nothing in the handbook as to battery specifications. In the U.S. you can buy the appropriate battery at AutoZone or Pep Boys, so you might want to check out their websites. Also, since you need to acquire a new battery get an AGM battery not a lead acid as you will get a better life out of the battery.

Hello all
I reply here, as I was asking myself the same question for XK battery specs some weeks ago.
My 2011 Xk also had the Oem battery installed when I got it: JLR part 6w83-10655-cc (made by Varta).
I dont think this was the cars first battery. Anyway I wanted to replace it with a new one, even though I wasnt getting any problems.
My initial problem was to find out if my 2011 Xk should be fitted with an AGM battery or not. My research googling for the JLR part number showed that my installed OEM battery was not AGM - HOWEVER, the available information is not abundant on this subject and I find AGM batteries made by Varta that look very similar to said Oem battery. At the end I replaced the battery in my car with a traditional flooded type battery from Vartas higher-class flodded battery line: Silver Dynamic 100A (eg. https://swissbatt24.ch/starterbatter...er=VSDH3-10012).
Car runs fine. No problems. However I had some questions about the charging voltage recently. Dont know if connected to my battery swap. Read here https://www.jaguarforums.com/forum/x...7/#post1890904 and here https://www.jaguarforums.com/forum/x...2/#post1896347.

Also buy something like a ctek mxs 5.0 conditioner to keep on the car when parked up.
Starting takes a lot of amps and short runs don’t recharge it so you can run the battery down whilst driving the car.
The ctek keeps it optimised.

Thanks. I have a Ctek and connect the car approx. once in a month. I use this car as a daily driver, ie. every other day or so I run it 30 miles on the highway.

I packed my CTEK away when I changed the battery on my '07 XKR and in the 3 years after that it only came out if I had the ignition on for a long time e.g. extended diagnostic sessions with SDD or if I was spring cleaning the car.
My '10 XKR has survived 6 months without me needing to use it. My only compromise is that I now lock the doors when parked in the garage which is a lot easier as the '10 has keyless entry.

I live 4 to 5 miles from work and use it most days. Apart from that I don't do great distances. In the 5 years that I owned the '07 I did 17,000 miles or approx 3,400 a year.
I was originally plagued with the usual electrical glitches with my '07 which is why I bought the CTEK I had been using the CTEK every week or so over the weekend but found that, apart from in situations mentioned earlier, I didn't need to use it after I bought a new (AGM) battery. I also didn't lock the '07 overnight so the battery was pretty abused!
The climate where I live in New Zealand is temperate so we get lows of -3 or -4 degrees centigrade overnight in the winter and highs of 25 or so during the day in the summer.
If my car was a garage queen and only got used a few times a month then I would definitely use a CTEK but don't find it necessary with my pattern of driving.

Thanks u102768!
I was interested to hear from someone who uses the car as a daily, as you do... and as I do myself. I would be quite astonished if using the car regularly (albeit with driving distances a bit longer than yours) would still result in battery issues. Obviously this is more of a subject for real garage queens that only see the road on weekends or summer season.
My other vehicles that are not used regularly - less than once a week - usually dont mind sitting without charging for a month. But that may be different with XKs, which prefer being hooked up to a ctek if not on the road regularly.
What would be the maximum period of inactivity for an XK (with standard battery and locked), before it needs to be hooked up for charging - 2 weeks? I dont have the car for enough time to be able to answer this myself.

To me, 4 or 5 miles sounds too short to recharge fully.
Mine if parked for some weeks shuts down even more and the remote fob is deactivated - but restored once door opened with key. (Make sure key works, at least annually.)

Interesting statement . Unless it is MY dependent I don't understand how this would happen. This past winter my 2012 must have sat for 2 to 3 months at at time . Never even started but sitting with the smart charger hooked up. Never had a problem using the key fob and in fact I don't even know if the hard key even works as I have never tried to use one. Just seems strange that your fob shuts down.

CTEK isn't anywhere NEAR enough, not even if you had ten of 'em hooked up.

I know, thanks, which is why I didn't mention programming modules in my post. I have a proper power supply for that but for reading codes and poking around you don't need anything but I still plug my CTEK in anyway.

You wouldn't think so but so far so good. My journey to work is 4.4 miles and it is all city driving at speeds of up to 60km/h and usually takes around 15 minutes.
My '10 XKR has a flooded cell battery rather than an AGM so I will see if it starts struggling at some point.

My XK 2011 was sitting in the garage for 20 days without driving while I was away. No Ctek connected. But I do have a fairly new flooded type battery in the car. 20 days non usage was no problem. Car started and behaved normally after starting.
