Replacing an 6yr old battery in mt 06 xk8, dealership wants $750, or i can buy one myself and have them replace, reset the codes for a total of $550 ($300 battery + $250 shop charge). lastly just go to batteries plus and spend $280 on a new battery and have them replace. My question is do i really need to spend the money to have the dealership install and reset the codes? Thanks

For about $200 at Walmart you can get a AGM battery made in Germany and it will fit. Make sure you vent it and take all the money you save and purchase a good trickle down charger. Your battery problems will be solved. There are no codes and I never have run into any reset issues.

should be no codes needing reset - the only thing to reset would be the stop points for window travel on the convertible. Replace battery, start car, radio off so you can hear and hold window switch down until you hear faint click, then raise window and again hold until you hear faint click. then do the other side

I was going to add that the "risk" in disconnecting the battery fully during a replacement is that you will reset the OBD monitors and fuel trims in addition to the windows limits. For some, getting these monitors to pass again proves difficult. It leads to a Check engine light and these monitors have to be reset again and the car driven for many miles in the hope of meeting the test condition. As already suggested look into keeping some power to these cable while you are replacing the battery so the various control modules never lose power. I believe there are cigar lighter adapters for this purpose, but I have never tried them. If it was me, I would try and maintain 12V with a spare battery setup in the engine compartment, between a ground and that 12V post at the fuse block.
Best of luck, keep us posted.

Not trying to be a wise guy but I have never had any issues in either replacing or disconnecting my battery. My car is a 2000 XK8 convertible. I never have had any codes or warning lights. It seems people are always doing hard resets without any issues, or am I just lucky?

I wouldn't say that. I'd say that a dealership is the last place to go to get a battery due to expense. But the dealership probably does charge $300 for a genuine Jag battery. The shop rate might be $200/hr, maybe more. They have to pull all the junk out of the trunk, the floor, the side panel thing, disconnect and remove the old battery, install the new, connect the vent and the cables, reinstall the floor, put all the junk back into the trunk, reset the windows, dunno about the radio. This might take $250 of seriously inflated rate shop time. I think the price is ridiculous, but I don't their they're being particularly dishonest.

Oh yeah, if it’s a convertible, it might take 30 minutes of futzing around to get the damn luggage barrier in place correctly.
Another oh yeah. , you want to get a smart battery tender, not a trickle charger..

On that note, I've read about this 'radio code' before when disconnecting battery. What does this mean? I bought a 2006 XK8 , without any manuals or documentation, so no radio code either. Will I need this code at some point in the future? And how would I get this?

If you ever need the code, you might find that it is written on the radio itself, or you can contact a Jaguar main dealer with your VIN number or there are some online services which can provide the code for a small charge.
