Power Drain when the car is off
Has anyone tried to measure the battery drain when the car is off? I'm curious of what the drain is when the car is completely off (that would include the key fob being far away since the system would react to it) whether it is greater than the "standard" 50mA.
I'm told that luxury cars run a little differently in this particular matter often consuming more than the non-luxury. It would also be interesting to know the difference in the drain between the base and tech.
I'm thinking of adding an Apple TV 3 (2013) through an always-on fuse. The new media boxes consume very very little power (about 0.8W) and to my estimates that would mean it would drain about 66mA which certainly it's more than 50mA but sure it could be considered NOT a drain if actual drain is larger than average.

Just be careful that in winter the voltage drop is harder to deal with since the car needs more cranking power to start up. Some of these battery protectors can be set at different voltage ranges. For example, one I think maxes out at 12V, but you may want to set it a little higher in winter to make sure you can still start the car. I haven't done a ton of research on this since I don't plan to install one but like most things you need to do the research.
