XF Battery

[tonycordon]

My 2013 XF 3.0S Sportbrake is telling me that the battery is low, and is switching off the climate control etc. My local indie is saying that when a new battery (I presume that's what is needed as a new alternator was fitted recently) is fitted the car needs to be 'told' that it has a different battery. So my question is, if I buy a new one from, say, Eurocarparts, etc. and fit it myself, will it cause any problems, I'm sure I'm not going to be the first to fit a non JLR battery to an XF! Has anyone had any experience of this please??

The modern Jaguars have a Battery Management System (BMS). If you ensure the battery is fully charged before fitting you can sometimes get away with it, but it is best practice to have the car 'plugged in' to diagnostics where the BMS can be reset so it can re-calibrate to the new battery.

I would just swap it out, then if you have problems go from there.

I can’t see the car not staring just because you changed the battery or it went flat.

Maybe all part of a cunning plan to make you go to a JLR dealer and pay £500 for a battery and £500 to fit it?

All this 'tech' should not be necessary.

This is what I did with my S-Type. I also connected my Li-ion jump-start pack across the leads to ensure that 12V was maintained whilst changing it. Worked for me!

Yep, I did this with my XF (Halfords Powerpack in my case). No problems after the change

Very probably.

I'll add the new battery malarkey to the already long list of reasons I have a twenty year old Jaguar and not a two year old one...
