Alternate Charging Terminal on XF?

I think it is because of the high amperage (current) that has to flow through to the starter that causes concerns. The wires from your battery to the starter are meant to handle this current, the thin wires from the fuse box are not.

Ok, Obviously, I agree it would not be wise to start the car via that conductor. The alternate charge point should be used to power the circuits to get in the boot!
We all have our particular insecurities! To an electrical guy, the Jaguar electronics do not seem so diabolical and sensitive. I laugh about the concern for which post of the battery to hook up first and so on. But, to me, the idea of dumping various snake oils into the engine or gas tank, "tuning" the engine, or changing an air filter from the manufacturer's design do seem a little foolish. We all have our quirks.

SUCCESS! Had the charger on trickle mode for about an hour and no power... Switched it to jump start mode and started to hear some clicking so I knew I was getting some power, and then I was able to pop the trunk!
Direct charger on the battery now, will check to see if it is shot.
Thanks Everyone!!

I've been told if you disconnect the battery there is a shitload of things that need to be reset ECU wise with a scanner bit ive also been told it will damage the ECU if i hook up a charger with the batter connected so intetested to know which way u did it and any problems.
Thanks

I hook my trickle charger up to the battery while it's connected to the car. Works perfectly and that's what they are designed to do. I rarely need it but if away for several weeks then I might do it to be safe
You can also disconnect battery if you want. It resets the window stop limits (easy to reset). And the clock. Sometimes the trip mileage too. No issues. There is claim about 'recalibrating' a new battery but I've never seen that as a problem
I would note that two people on here mentioned more serious issues with electronics when re-connecting the battery. Seemed to fry a module. Maybe they spiked it or some other issue. But my bias would be to leave it connected and trickle charge away!
Note - if you do disconnect the battery, don't close the trunk...

Try the key from the fob. In the door (pull off piece of door handle) you will see a place where the fob inner key goes.. open door and drop down back seat to enter trunk. Pull trunk safety string and open trunk. May be different on some models.
