Is the battery new? They usually only last 4 or 5 years.

I think my new MB battery ran about $150-ish...

Find a good independent Mercedes-Benz shop to have your car diagnosed.

I had my shop install an OE (Mercedes-Benz brand) battery.

you can pick up a really nice red top optima battery from Costco for like $150. it is a gel battery and should give you more reliability and more power too. if it is not the battery it could be the alternator. have MB check and make sure it is putting out the required amount of power.

Looks like a battery problem, but it might be an alternator going wrong...maybe...
