Jaguar XK Battery Replacement
#1
![Thumbs up](https://www.jaguarforums.com/forum/images/icons/icon14.gif)
A few months back I asked my local Jaguar dealer to install a new battery that I had purchased from a local autoparts store. The battery recently went bad (voltage dropped by more than half under a load test), so I returned the battery under warranty and received a new replacement.
After some thought I decided that I could buy a whole lot of beer for what the dealer installation charge would be, so I decided to do it myself. Knowing the battery was located in the trunk under the liner was a bit intimidating to me, but I decided to "go for it".
It could not have been any easier.....!!
So for any who might be interested, here goes:
1. Open a beer (preferably Guiness in honor of this fine car)
2. Remove the floor panel over the spare tire as well as the luggage cover (resembles the cargo cover one would find in an SUV). Lift the luggage cover up and out.
4. Remove the four round plastic knobs at each corner or the vertical panel facing you at the rear of the compartment (the rear of the back seats) remove these by unscrewing counterclockwise, pull out, and put in your pocket.
5. The vertical panel will now come free when pulled to reveal the battery directly in front of you.
6. The battery has security bolts on the front retaining bar and 10mm bolts on both terminals and the right hand safety retainer.
7. The positive terminal is on the right, the negative terminal on the left (don't forget to plug the vent hose into the side of the new battery).
8. If you do not first attach a power source to the car's electical system, you will have to reset the presets (radio stations, etc). This took me very little time (5-10 minutes).
9. Reinstall the trunk liner, etc.
10. Drink your second beer.![Smile](https://www.jaguarforums.com/forum/images/smilies/smile.gif)

Timely post, I'm in the same boat. I believe my 08 still has the OEM battery and after my Nav/Audio/LCD screen locked on me twice (the first time the dealer claimed they needed to wipe a=the cars software and re-load which took about 6 hours) I pulled the negative cable on the battery the second time. That returned my LCD screen.
All I know is the battery is ALL black with no visible markings. I'm told they are on top of the battery. Can you confirm what the OEM battery looks like?
I'm looking to buy an InterState AGM replacement.
Again thanks for the great post.

Finally got around to looking at the battery, what a PITA to get to and see the top. This is exactly what is in my car, of course there are no month/year codes that would tell me if it's the original OEM or a newer replacement battery.
But after two episodes of my Nav LCD screen/system locking up I wonder if that wasn't the battery telling me it's time to be replaced.
Correct me if I'm wrong but isn't battery replacement covered under the B2B warranty?

So, you should be covered under your warranty.

a fun fact , i bought optima yellow top thinking one of the best , but both optima and varta are made by johnson control and varta oem battery have same technology ,
Johnson Controls Inc. | Brands
oem 650 ca , 90ah , 170 reserve capacity battery is pretty gud , the one made in 2002 is still in my 03str and cranking strong after 8 years , new one is 202$ from dealer + tax , will go for the oem only on the day it shows weakness
the oem specs for german cars are very very high compared to aftermarket specs in US , so i will go with oem from dealer anyday and price difference isnt much
i got d34 yellow top for 208$ + tax(after our shop discount ) , and it has lower AH and Reserve ampere rating then oem and more expensive , returned it seeing the lower ratings and after finding both brands are made by same company ,
my battery died on me once , i drained the battery listening to music too long , was trying to program the garage door opener , took me 2 hours , bummer :P AFTER that battery wasnt picking up , cranked with laziness and felt it was dieing , thought needed new one after serving 8 years , got yellow top but returned as soon as i got it ,
then tried professional battery charger at our shop , has been fine since ,its 9th year now from its manufacturing date stamped at bottom , i find it really hard to believe
