2011 GL450, '06 R500 traded, '08 ML350 sold
First off, if you have a 2007 ML350 then it is a W164, not a W163 so you posted in the wrong forum.
If you changed a battery two months ago, and today you needed a jump then one of two things are happening. Either you have an electrical component draining your battery (could be all sorts of things like bad alternator, or smaller things like one of your components keeps running after motor is shut-off draining the battery) or you got yourself a bad battery two months ago. Assuming you got the correct type battery installed from the dealer or a reputable parts source that was able to cross-reference the battery to your model I'd say you got yourself an electrical component draining it.
So no, MBs didn't come equipped with batteries that only last 2 months!
