C5 Current draw
Does anyone know the actual current a C5 will draw while sitting idle? I've heard a C5, due to it's extensive electronics systems, can actually totally drain the battery if sitting idle for 2-3 weeks. I recently purchased a Float charger to maintain my battery, and I was curious if the 0.5 amp charge rate will be sufficient to overcome any battery drain.

All GM vehicles must not draw more than 500mA. Anything more than that will drain the battery dead. After all systems shut down, it should be around 15-50mA.
