My question is, do you think its safe to use on the XF, with the car being so finicky with electronics, I thought I would ask you all. Thanks
If it charged to 12 too quick the battery is shot and will soon let you know.
Get another battery and feel confident when you go out. Batteries are cheaper than a tow home anytime.
