'06 s-type 4.2 VDP. The battery was original and giving no problems - yet. Seven years old, though, and his forum is loaded with cautionary tales about weak batteries. There were no problems after replacement with idle, clock, radio or any other settings that I could see. All I had to do was reset the window limits. On to installing voice!

 

Ya mine had a weird issue once with Nav, I checked the batter to see how old it was. It was pushing 7 years itself so I just replaced it and never had another issue! Some things are better to replace before they fail!

 

+1 regarding timely battery replacement as pointed out by Michael Star!

 

2000 XK8 - Are there any issues to be concerned with by replacing a dead battery?

 

I doubt it but the XK forum is a better place to ask!

 

On the topic of power, though not the battery in particular, but, my alternator failed Last Thanksgiving. As a result of not having the proper charge, my car threw every code known to a Jaguar, Transmission failed, Park Brake Fault, Engine Failure on and on and on. Jag's seem to be absolutely dependent on consistent power. (Mike), my battery was 7 years old also. It's the same one that was sold with the car originally in 2005. I bought another Jaguar Battery at 187.88 plus new protectors and the labor to put it in totaling 240.00 because if I can get 7 more years out of it, I'll consider myself fortunate.
