Thats actually not uncommon for a battery to run out of juice after sitting for a while. What is uncommon is the amount of time that elapses in your case. It shouldn't be empty after a week. However, this is assuming that you have a "Good" battery, or one that starts out at 100% before you leave your ML for the week. Factory installed batteries usually need to be replaced after 3-5 years. If I were you I would get the battery checked at AutoZone.

In the rare case that you have a 100% "Good" battery, you may have a constant draw from the battery when the car is off. This is highly unlikely. Check the battery out, and report back if you have any more questions!

I stored my mercedes for 4 week and the battery is dead it is normal

Yes, it is totally normal for your Mercedes battery to go dead after 4 weeks of non use due to the onboard computers that drain on the battery. I store my Mercedes for up to 5-6 months at a time. The solution is to install a battery tender that plugs into a power outlet in your garage and this will maintain proper charge in the battery and then will shut itself off until the voltage drops below the threshold again , then will kick on and bring the battery up to full charge. Any auto parts store, ie. Napa, Auto Zone, Pep Boys, etc. carries them. Cost is approx. $35-$45 and take the average person 1/2 hour to install.

I am leaving my 2000 E320 Mercedes in my garage in Florida for 5 months. Do I disconnect the battery or use a maintainer?

If you had the choice and are sure that the maintainer will last till you're back, then I would recommend the maintainer as it would be a hasle to reprogram all your settings if you disconnect your battery.
