If the temperature is above freezing (e.g. in a garage), good battery should remain in working order over 2 week period. If your battery is relatively new, I'd say you have nothing to worry about.

wow, one month ?
Dema,
This probably is a good record -- one month. I will consider having longer vacation now.
Both you and Gethen mentioned that it will not be a problem for a new battery but my car battery is getting older after years while my vacation will not be shorter. Is there a long-term solution? I know I can always call MB roadside assistance for replacing a new battery free within my warranty.
which I did it before but I had to drive my car back to the service center to reset settings after replacing a new battery.

The answer is trickle charger
I live in a cold climate area where batteries die regularly. For the winter months when there is little use a trickle charger does the trick but it means your vehicle has to be parked near an electrical outlet.

my dealer said trickle charger does NOT apply to the new e !!!
northbenz,
You are right for most of MB models but I just confirmed with my local dealer, the technician said the trickle charger does NOT apply for the new e models because there is a chip inside the car is not compatible with the current MB trickle charger. and he suggested I disconnect my battery before I go to my vacation and synchronize both windows and roof after reconnect the battery.
I believe the trickle charger for new e is on the way, I definitely will get one after it is available. Does anyone when it is available and the part number?
Thanks.

2 batteries--regular and reserve
jim256,
I was told that I could disconnect the battery in the trunk as long as I want and I believe this is the one to provide the electricity power for start engine. The other one holds all memory setting, e.g. my memory seats, radio stations, etc. When I reconnect back the battery in the trunk, the only things that have to do is reset/synchorize windows and roof.
The way you resynchorize your windows (4 of them) is
after you reconnect battery, press window button down and hold it 3 seconds then press up. (you have to 4 of them)
for the roof, press open button then it will pop up and hold the button 3 seconds then you close it.
I hope MB comes out trickle charger for new e soon. I don't want to get a shock when I disconnect my battery in the trunk. By the way, after fully charge your car battery, you always get better lights and sound quality. especially, for those who drive car in a short trip daily. (it should be charged over night every 2 weeks or 1 month depends on how short your daily trip is and how you consume the power, e.g. heated seats, lights, etc.)

disconnect
i usually just disconnect the battery.
if it's a 2 week trip, i would keep the battery connected, lock the doors, but not enable the alarm. if you have your own garage, it should not pose a large security risk. the alarm uses up some battery (much more than the other stuff that it uses while shut down).

I don't see where is the big concern. A new battery should hold enough chage for month.
I have an old Vette with a 3 years old battery. The car has been sitting outside since Sept.5th and we had very cold weather (minus 22deg) for a few days)
I started the car this afternoon to put it in my garage for the winter. It cranked righ up. 2 -3 weeks on a new battery is nothing

NOT NECESSARLY ..... IF YOU KNOW HOW TO DO THEM YOURSELF
DSMIT,
What do you mean if you know how to do them yourself?
and how?
if you replace a battery, it is NOT only resynchronize both windows and roof, you have to reset your break, etc. -- it is controlled by electricity, after you lose electricity, it works by press pedal harder but for safe reason, your car will display malfunction of your break and ask you to visit service center. I believe you have to use a computer/laptop from service center to reset it. actually, if you lose electricty totally, you will find you CANNOT turn your key to start the car, system locks the car for your safety -- you have to call roadside assistance but after a battery replacement, the technician will ask you to visit the service ceter as soon as possible.
when I said disconnect the battery in the trunk, you only disconnect the negative cable from the battery -- the one close to the you. hopefully, I do NOT mislead everyone for the definition of "disconnect" battery.

on the user manual page 266
what a hack of this user manual, on page 266
well, it mentions "batteries should always be sufficiently charged" but it does not show me HOW ??? and it mentions you will need to have the battery charge checked more frequently but again it does not show me HOW ???
there are more information on page 344
but where the mb trickle charger for w211 ???
this page also answers NuBenz's questions
on page 345, this explains DSMIT's DIY
on page 104, it talks about read head restraints NOT front seat head restraints ???
on page 75, does anyone see the way to resynchronize the esp ???
the easy DIY way as I known so far is drive it back to service center.
as northbenz said, the trickle charger is the solution and I hope it is available soon. with this accessory, you can
1. have a looooooong vacation, i.e., one year long.
2. make your battery life loooonger if you charge it bi-weekly or monthly.
3. better sound quality and brighter lights.

these batteries should always be sufficiently charged in order to achieve their rated service life. if you use your vehicle mostly for short distance trips, you will need to have the battery charge checked more frequently.
there are more information on page 344
charge battery in accordance with the instructions of the battery charger manufacturer
this page also answers NuBenz's questions
1. the brake boosting effect is not available. you need more power to brake and brake pedal travel is increased. if necessary, you must depress the brake pedal with full power.
2. you can no longer turn the ignition key or, in cars with keyless-go, pressing the keyless-go button on the gear selector lever has no effect.
3. the gear selector lever is locked in the position P.
2. you can no longer turn the ignition key or, in cars with keyless-go, pressing the keyless-go button on the gear selector lever has no effect.
3. the gear selector lever is locked in the position P.
1. set the clock, page 136.
2. resynchronize the front seat head restraints, page 104.
3. resynchronize the esp, page 75.
4. re-enter the radio code.
5. resynchronize the side windows, page 186.
6. resynchronze the sliding/pop-up roof, page 189.

confused ???
I called mbusa this morning and the advisor told me it is no problem for installation the trickle charger into w211 but I was told by technician in my local service the other day because of the chip in the w211, new e cannot have the current mb trickle charger.
but I got the price quotation of current MB trickle charger, $67, plus tax. the installation fee is $95 times 1.5 or 2 hours. (labor $95 per hour and it takes 1.5 to 2 hours to install it.)
northbenz, could you comment on it?
thanks.

I think you want to be fairly careful about messing with the electrics (including battery) of the newest M-Bs, like the 2003 E-Class. I have picked up chat about resetting the airbag sensors that only main dealers can do; not just like re-synching the windows.
But I would like to hear more on the subject. I am considering buying the new E55 (in Europe) but it will have long dormant periods. Normally, my storage guy disconnects the battery (of my 500E). This has worked a treat, but I am not sure I will be able to do the same on the next car.

koz4sure,
after reconnect back the battery, if you do not want to mess up with the electrics, just drive your car to a local dealer who can reset the settings within 10 minutes -- it is free.
