I'm using the CTEK MULTI SS 3600 plugged into the power socket under the dash of my new Plus 4SS. Works well. I had a flat battery before I started using the charger; I guess it was a case of putting the car away with a partly charged battery and leaving it for a week or two. What I don't understand is why Morgan's immobilisers flatten the battery when other cars' immobilisers don't. Does anyone know?
