Recommend a CTEK battery maintainer. It is well recommended on this forum and comes with handy connectors to install a permanent pigtail for quick connect/disconnect.

I see there is two batteries one big and one small I connected the CTEK to the big one and they both get charged? What is the small battery for?
I've had a CTEK MUS4.3 on my 2013 XJ for many years with no problems, and have separate pigtails for the primary battery and the small stop-start battery as shown in the photo below. The CTEK is connected to the primary battery and the orange/black connector for the stop-start battery is seen towards the back of the trunk. I occasionally connect the CTEK to the stop-start battery to keep it topped up. When I do so, I change the CTEK from the car icon setting to the motorcycle icon.
I routed the CTEK power cable over the right rear fender, in between two pieces of plastic trim as shown below. The trunk lid closes over the power cable with no problems.
The CTEK sits on my garage floor. It's plugged into a 120v wall socket. I've used it almost every day for the last 8 years.
If you plan to install a CTEK (or any other brand of battery maintainer) on your XJ, note that the negative (black) pigtail MUST be connected to a chassis ground. That's because the Battery Monitoring System Module is connected directly to the battery negative terminal, and it will be damaged if a battery charger is connected to that negative battery terminal.
JaguarXJL15, for your information now that you know about the small battery, if you wish to permanently disable the stop/start feature, simply disconnect the small battery negative to chassis ground cable.

Yep, that works, did it myself on my F-Type the very first day I got it home.
Then a few years later I completely removed the small battery.
Both things had zero effect on anything other than to permanently disable the stop/start system.
Also the original main battery is still going strong at over nine years old. Mainly due to regularly hooking it up to a battery tender/maintainer but maybe getting rid of the stop/start battery has helped.
Hey OzXFR I got ten years from my factory battery so your close!
I need to disable my start/stop again too because the main battery replacement made it start working again.

Wow. Y'all gettin' 9 - 10 yrs on the orig battery!
I've always thought that 4 - 5 yrs was pretty good for a battery.
I've only trickle charge on my factory 5 yr old battery maybe once a year, using CTEK. Would that be enough, or try to use it more often?
BTW, just in case, what's the correct part #, or size, for replacement main battery?
Any recommendations on where to buy & brands...?
Thanks,

good to know I thought there was no way around the annoying start/stop I think its more of a gimmick not fuel saving

I connected the negative black to the negative black on the battery yesterday for a few hours I hope I did not do damage can you show a picture of where you have your negative connected to? anywhere on the bottom or side of the truck?

Follow the primary battery negative cable (black, round, and thick) to the gray nut where it is grounded on the fender. Loosen that nut and attach the CTEK negative pigtail to that bolt, and tighten the nut as shown below.
Note that if you attach your CTEK to the stop-start battery you can attach the negative pigtail directly to the negative battery terminal because it doesn't have a Battery Monitoring System Module.
this ctek charger is useless I've had it charging the battery for days and I still get a low battery warning the battery is not original its already been changed so I doubt its the battery thats the problem

I have more confidence in your CTEK 3300 than your XJ's battery. Just because you have a new battery is no guarantee that it can hold a charge or that your alternator is properly charging it. You're in Canada, where cold weather is a battery killer.
Use a voltmeter in the morning before you start your car to measure the battery's voltage. It should have at least 12.6 volts. If it's less, it should be replaced. You should also have your alternator checked. If all your driving is short, without any daily highway driving for at least 15 minutes, then your battery isn't getting fully charged.

The battery is not new I just know it is not the original when It was changed I do not know I recently bought the car from a dealership and it was sitting in the parking lot for a month I have not driven it much either no highway driving yet I'm waiting to get all the overdue maintenance complete
I hooked up a voltmeter today the battery was connected to ctek all night the charge was 12.5/12.6 when I unlocked the doors it went to 12.1 and stayed there I guess the battery is dead and not able to charge time for a new battery or the ctek is defective and not able to charge with the Ctek connected to the battery the voltmeter measurers 13.7
Recommended battery 49AGM 900 CCA 160 RC 95 AH?

That's the correct AGM battery. This is from Costco, and costs $169.99 in the USA. Most car batteries are manufactured by Johnson Controls, so shop your local auto parts stores in Canada and you may find a better deal on the same battery with a different brand name.
Since the factory battery lasted 10+ years I will be surprised if this after market one lasts anywhere close to that. That was a record for me and batteries!
