Mercedes Benz 300e Battery Problem
This car has a new battery. The alternator is putting out 13.2 volts, but after driving it for a day and a half the battery is dead. Why is it doing this?

13.2 volts is way too low. The voltage must be between 13.75 and 14.75 volts. You're running off the battery which won't last long.
