Battery Swap

Battery Swap
Hi all
My XK is now approx. 7 years old. It has an OEM battery installed, but I don’t know if it is still the first or if it was replaced by the former owner at some point in time.
However I drove the car for 200 miles and the next day, after turning the stereo on for 5 Minutes without engine running, the system advised that the stereo will shutdown in 3 minutes due to low voltage.
I then measured the voltage at the battery, still without running the engine. Result: 12.2 V.
Does that mean I should start looking for a replacement battery soon?
If replacement advised: has anybody tried to swap the main battery while another car battery is hooked up with jump start cables to the positive/negative terminals on the left side of the boot - i.e. to avoid power loss and deleting of all memories and settings? Any reason this is not a good idea?

VERY SOON, like yesterday :-)

Me, I don't bother with a 'memory holder' as the only thing lost on a battery change is the Window Settings, which take literally fifteen seconds to reset. Everything else is still intact, such as all Nav stuff, all Audio stuff, Seat memories, oh heck, I think EVERYTHING stays EXCEPT for the Windows.

I have today swapped the battery. The measurements above fit (100Ah Varta battery) but the OEM Jag battery (90 Ah) that I got out was a tiny little bit lower that this Varta, approx. 1cm. Otherwise ident measurements. They both fit flawlessly.
I btw used my motorcycle connected with jump cables to the +- terminals in the trunk to avoid power and memory loss. It worked without any problems.
Regards!

The Jag OEM battery depicted above looks like a standard wet no-maintenance lead 12V battery to me. Nothing fancy like AGM or similar. Also the replacement battery I used is a OEM-quality standard lead battery by manufacturer Varta/Johnson Controls.
Did Jaguar in 2011 or later ever put from factory AGM batteries in its cars, with the specific charging technology in place and with replacement batteries also in need to be AGM spec?

Yes, Jaguar did and does fit AGM batteries to its current cars (no pun intended). My F-Type has its original AGM battery.

I was told by a service tech that Jaguar started using AGM batteries when they started with their start/stop technology. First as a secondary battery used specifically for the stop/start feature then as the primary battery. They also changed the alternator/ECM profile to accommodate the AGM . He never recalled seeing an X150 delivered with an AGM . Don't know if this was true but that's his story.

Dear Dave,
one question: even if you find an AGM battery that fits in the XK, would it not be necessary to adapt the charging technology a little bit to make sure the load voltage is correct for AGM? I understand that AGM requires a different loading voltage than traditional wet batteries. But I am no expert...

Hi all
for future reference I would like to link to the following thread here on the forum which provides most up to date information AND a link to Jaguar‘a TSB on the subject of AGM batteries in XKs and how to identify them:

Some more details on the JLR OEM battery to be discussed:
When you read the TSB on how to identify Jaguar OEM batteries as AGM or not-AGM (see here https://www.jaguarforums.com/forum/s...2&postcount=19) it seems pretty clear, that the following battery is a traditional wet non-AGM battery:
HOWEVER - there is one point of doubt that I have
in this regard, whether this really is a traditional
non-AGM flooded batterie. See my next post... (technical issue)
