just changed battery to a Varta , when i start the car , the andriod mirror stays on . but the LED intirior light still flashes when crancking .Have you got the biggest alternator and battery fitted? I see there's a 225 Amp alternator that fits some model of the Mondeo. You've identified the problem - not charging enough while driving. The solution would be charge more. That needs a bigger battery to handle the current without breaking down. You will not charge more by fitting capacitors, the battery will deteriorate if it's not getting enough charge, the capacitors just delay the point where the battery stops working. I don't like the idea of 'warming up' the engine - sludge condenses in the exhaust and 5 minutes driving may not blow it out. Best to drive off after a few seconds when the oil has had a chance to get pushed around. How long does it take to crank the engine? is there a problem there? my petrol car cranks for 0.7 seconds according to the mechanic (the printout from his automated electrical system tester), the alternator will put that back in the first 30 seconds of driving. I think you need to fix the cause of the problem rather than bandaiding the symptoms.
i feel if the starter motor could be worn and demanding too much amps to push
