Secondary battery

[Carl Grundy]

Hi all

During a car service I was advised to.  replaced the main battery on my Jaguar 2.2 XF 2013 premium luxury which has been done.

Prior to having the service i had no heated seats, wing mirrors not defrosting along with rear window which is still the case.

i have been told I need to replace the secondary battery is this causing the issues I am having with the above?

Hi Carl, not sure if your issues are battery related, but might be.

Have you checked the fuses, sounds like a circuit is out of synch.

If your secondary battery is still the original from 2013, presumably your main battery could also have been original equipment, then I would go for a replacement of the secondary battery. Modern cars, especially Jaguar are VERY sensitive to voltage fluctuations and a poor battery is a prime cause of these.

I believe the secondary battery only comes into play to feed the voltage sensitive circuits when the car is operating in start / stop mode. Does your start / stop mode operate under normal circumstances?
