Post another belt question

ive asked before, but after doing some online shopping i ran across a site for the belts just to see if i could get them cheaper online.

now my alternator has two rows for belts. they both go to the crank. do i absolutely NEED both of them on? i am only using 1 right now as it seemed redundant to use 2 of the same thing.

it says : "Alternator This part number as sold by Mercedes represents a belt set. As this is a reference number, 2 belts of this size are required."

if so, why? could that be the reason for my alternator/battery drainage problem?

Having one belt instead of two wouldn't cause your alternator to produce less, unless the belt is slipping. You'd hear it squeal if it was.

If memory serves, and admittedly it's a dimn one, two belts were to balance the rotating shaft...
