Mercedes-Benz SL55 AMG Battery Drain

Has anyone else encountered a problem with their battery losing a charge when the car is sitting? Richard asks:

A problem has plagued my SL55 AMG for the last 2 years. I have since brought the MB AMG to service twice for the same problem. This last time the service mechanic replaced my second battery found in the trunk and gave me a battery conditioner that needs to be connected to the battery when the MB AMG is sitting. The manager notified me there is a drain on the battery that they cannot find. Is this a problem all ’03 SL55 AMG’s have and if not does anyone have an idea why there would be a constant drain on the second battery, and is there a fix? – Richard
