How to access battery for charging?

Hi
I am getting ready to store my XKRS for the winter. In addition to pumping up the tires and adding fuel additive, I'd like to connect a trickle charger to the battery. How do I get access to the battery terminals? It's was not very clear from the owner's manual.
Another option could be disconnecting the battery completely and storing it separately inside a more controlled climate environment inside the house. I'd like to hear from people who are in a similar situation. What do you do?
Thanks

Ah - timely post. I'm just finishing-up a 'Battery FAQ' for the XK. I'll get it posted today or tomorrow...
However, what I'm about to say on Battery Chargers:
>>>
The auxiliary power socket (what was called the Cigar Lighter socket back in the non-PC days) is not live when the systems are shut down, so can't be used for charging.
I recommend connecting a battery charge lead directly to the existing threaded studs on the battery leads. I used a Battery Tender Ring Terminal harness with fused plug
(Amazon Battery Tender 081-0069-6 Ring Terminal Harness with Black Fused 2-Pin Quick Disconnect Plug) together with a Battery Tender 25ft extension cable (also available in 12.5 ft length)
(Amazon Battery Tender 081-0148-25 25' Quick Disconnect Extension Cable).
The Ring terminal harness attaches to the threaded studs on the battery leads with 2 * M8 (metric 8mm) nuts. It has a 7.5A in-line fuse and about 2ft of wire.
It plugs into the 12.5/25ft extension, and that easily reaches my charger. The cord easily passes under the weatherseal of a closed trunk
I keep the excess wire coiled in the spare wheel well.
Ensure the connector is insulated or covered when not in use, and this lead MUST be fused (and as close the battery as possible), since it is live at all times, and bypasses all the car systems....
I plug my maintainer in overnight, once a week or so, but some member (like Richzak and Stuart S) leave theirs plugged-in all the time.

100% correct. It's an easy 5 minute hookup to the battery post studs.
Great guide/photo for hooking up the battery trickle charger......

I prefer using the remote battery terminals in the trunk. I leave those wiring leads connected all the time and simply plug my maintainer into the quick-connect terminal in my trunk. Quicker, easier, and safer than connecting directly to the battery.

I just get a Batery tender on my cat few weeks ago before I stored it for the winter. The dealer installed it when I went for the oil change before storage..
The battery is such at a bad place, it seem to me much more simple to get the mechanic install it. They charged me 99 $ for the charger and about 1 hour the install it. I could have save some money buing a charger on amazon (69$) and install it myself, but I was rushed and no time to do it. Anyway, if there is a problem, the dealer should be rsponsable.
No trouble, 200 $ and it's done. Just plug it on an extension, and your OK for 5 months... At spring, I will have just the connector (about 4 inches long) in the trunk...

The chargers that most Jaguar dealerships sell is the CTEK with the Jaguar logo on the cover of the charger as seen below. You can buy a CTEK 3300 on-line for under $60.00....hook it up yourself, saving almost $140.00 to $150.00 US

Weel, Rich, you're probably right, but I'm rally rushed on the business now and I don't have much time to loose to find my way to fix that charger in a so stupid place to put a battery in a car. I can figure it's more central to put the batery under the folded roof, but man, what a weird place.
When the dealer just ell me he can do it for me, I just say OK and moved on...

I keep my Battery Tender on a small piece of formica on rear shelf where I can see it by just looking thru the rear window (Coupe).
Just another reason why Coupes are superior..................
Battery location is great; it's clean, cool and away from gasoline and only takes 2 mins to gain access.
Do have to admit my wife's XK8 has a little better access (still in trunk, where it belongs!).
Cheers, Adrian

I don't understand why so many of you connect your chargers directly to the battery terminals when it is so much easier, faster and safer to use the remote battery terminals, which is what my owners manual recommends when using booster cables.

I am not sure about the safety aspect. I really can't see how a direct connection would not be safe. I have never heard or read about a potential safety issue using a direct connection.
My wire harness from the CTEK comes out of the rear battery compartment and looks great. I just unscrew the 4 plastic thumb screws and the panel is removed.
Trickle charging is highly recommended due to the fact that the charger emits a very low voltage to the battery.
Batteries can explode for many various reasons as they could emit hydrogen gas.
My battery is a Delco sealed battery. The CTEK 3300 will automatically shut down when the battery is fully charged, thus it is considered a "smart" charger. I am relying on the technology of the CTEK 3300 charger and there proven results. I cannot find anywhere that the CTEK 3300 caused a battery to expload.
From CTEK.....MULTI US 3300 operates in a three step fully automatic cycle IUoUp. It starts the charging with an almost constant current (0.8A or 3.3A) until maximum voltage (14.4V or 14.7V) is reached. At this point the charger switches to constant voltage, and the current supply to the battery is gradually reduced. If the current drops to 0.4 A, the charger switches to
pulse maintenance. If the battery is charged and the terminal voltage of the battery falls to 12.9 V, the charger automatically starts again at the first step of the charge characteristic. The MULTI US 3300 measures both voltage and current in order to determine out whether the charging process is finished or whether a new charging cycle must be started. Various methods are used, depending on the time of the measurement.

Frankly, I am surprised to hear that some have had trouble with the Battery Tender brand charger. I personally own 4 of these, and have had no trouble in 10+ years of use. Motorcycles, hot rods, Jaguars... you name it. Now, admittedly, I have the "original" style Tenders in the metal case. Never had the small plastic one. I have also used and installed the Ctek chargers. No problems there, either. The Harley dealer I used to work at installs Tender leads on every bike before delivery. They also used the Tender Multi Station chargers for our inventory. Never a failure. I recommend them to all my friends.

Is the 2 foot chord long enough to drape outside the Coupe trunk to connect to any extension chord or........do you need that 8 ft extension they sell on Amazon to get it out of the Coupe trunk and have the trunk close tight? Will any typical extension chord work with the chord that comes with the CTEK charger? I just ordered the 3300 from Amazon.
I have the same CTEK 3300 on both the Jaguar XKR and Porsche 981.
I highly recommend the 8' CTEK Comfort extension. You will most likely need it. CTEK suggests NOT to use an extension cord from the electrical outlet to the charger plug.
Here's the link.
You use the heavy duty cord from the charger directly into the electrical socket. The other end, with comfort extension, and round ring battery terminals go direct to the small battery posts, or you can connect the way that Stuart S has shown in his photos here.
Either way, you will never have a low or dead battery for many years ahead, until the battery just wears out.
The CTEK 3300 will be the best device you buy for the new XK.
