I am not certain how the Mercedes trickle charger should be hooked up to the battery of a 2008 S600. Any help would be appreciated. The car has two batteries: a starting battery in the engine compartment and a serving battery in the rear that keeps the electronics of the car running. I have been told that this serving battery can be 'reached' by attaching the trickle charger to the poles found adjacent to the starting battery. The + clip to the third from the left pole and the - clip to the far right pole.

Is this correct?

Thanks in advance.[/align]
