battery dead after winterstorage read this!!!
hi I always keep my car in garage during winter,i have no electric sockets to connect the charger to the battery,so every winter my battery gets empty,when this happens the car will loose all memory,then i noticed something on my audiodeck,I had to enter the code again so it could work properly thats what i thought.so i went for a spin with my car i put my favorite tape after a while the stereo just died,press on/off button it worked,then died again,this also happens with cd-changer and radio they also die.The solution is you have to go to the dealer and set up the computer to get new software so the stereo will work properly,this means evreytime the battery dies and there is no power anymore you have to go to the dealer and feed the car with new sofware it costs me around 140 $$$$$$$$$$$$$ to do this lousy job 
also your automatic trans will suffer from lousy shifting if you have the electronic trans

You can run into a whole host of problems when the battery dies. It would be worth your while to run power to the garage if you can, and use a battery maintainer. See http://www.benzworld.org/forums/audi...y-charger.html for some discussion.
I don't know what your car is - but here is a link to some of the resets one may have to do in some models - see post #14 at http://www.benzworld.org/forums/show...30#post2216730.

A battery suffers permanent damage when it is permitted to discharge below about 70% state of charge. The battery plates will build a layer, called sulfation, which is not removed when the battery is recharged. The sulfation inhibits electrical flow, effectively decreasing the cold cranking apmperes available from the battery.
The rate of plate sulfation is proportional to both state of charge and to temperature. Time is a factor, so if a battery is quickly discharged, then recharged, then sulfation is not an issue.
To maximize battery life, ensure a stored battery is fully charged, with the electrolyte level properly maintained. To ensure acceptable battery life, ensure the battery remains above 70% state of charge. A battery will self-discharge about 10% per month, plus any connected loads.
A lead acid battery may be stored indefinitely connected to "float" voltage of 13.8 VDC, by maintaining the electrolyte level.

I have no idea of the physical layout of your place - but I just added two circuits to my (attached) garage last month, and one in the attic for additional lighting, and two more in the interior of the house for lighting effects. If you're not handy or feel unsafe doing that, an electrician is less expensive than a new battery and the problems you may begin to have.
