Prodigy Parasite?

[Red-Rover]

A couple of months ago I purchased another vehicle in order to save miles on my towing truck. The truck now sits for long periods without running (charging battery) and I am wondering about parasitic power loss. Does the Prodigy brake controller draw power when not in use?
I know a battery maintainer would keep the battery up but I can just visualize myself backing out of the storage shed with that thing still plugged in.

Your vehicle most certainly has parasitic draws other than the brake controller. The radio, remote door locks, and many on board computers are just a few examples. The best strategy for the health of the battery and the vehicle mechanicals is to drive the vehicle every few weeks..
