	* A quiescent or parasitic drain usually shows as a flat battery after the vehicle is left standing for a considerable time, such as when the owner is on a vacation. A battery in good condition should last for several months with the vehicle locked and still start reliably at the end of that period.		* A quiescent or parasitic drain usually shows as a flat battery after the vehicle is left standing for a considerable time, such as when the owner is on a vacation.

	The W220 S Class only has one main battery. Some other M-B models have a secondary or auxiliary battery which is used to maintain the electronics whilst cranking the engine. This arrangement eliminates the need to reset various ECUs after removing or changing the main battery. A technique may be employed to maintain a 12V supply on the ECUs when replacing the battery.

	Thorough quiescent current draw can be performed by making a current sensor by manufacturing a very low resistance resistor out of a piece of coat hanger and inserting it into the main battery lead. Then a normal Digital Volt Meter (DVM) can be used to measure the voltage drop across the resistance.
