Sorry if this has been done before. I have a xf 3ltr v6 lux diesel 2012. I’m told I can’t take the battery off the car to charge and need a ctek charger. Can anyone please tell me how to charge my battery and what the process is please. I have a standard battery charger already. 

I think your car will have auto start / stop function and therefore you will not be able to use a "standard" battery charger. You will need a charger that can accept AGM battery technology. Typically these are of the C-Tek or Ring Automotive variety.

You should be able to charge the battery in situ, with the correct charging equipment. You can connect direct to the battery terminals, or there may well be remote connections within the boot area. Typically the positive remote terminal is behind the vent panel on the NSR quarter inside the boot. The negative remote terminal is generally under the boot floor, in the spare wheel well.

Hi

"You can connect direct to the battery terminals"

Just a slight correction to above. My understanding is that you should NOT connect directly to the -ve earth terminal on the battery itself, but to a good body earth point. I use the spare wheel mount. The Battery Monitoring Module sits on the -ve battery connector and so if the charge current by-passes it rather than flowing through it gets confused as too how much charge the battery has 🙂

Jim is spot on saying you will need an AGM compatible charger. I use the CT5 START/STOP and have a CTek extension which runs into the boot above all of the floor covers so I can just "plug and play". IMHO it is worth doing a regular top-up charge as these are VERY battery hungry cars.
