Subaru dcm battery drain
Parasitic Draw: This is the amount of current flowing out of the battery when the vehicle is "off" or "asleep." It has other names, such as Dark Current, Dark Draw, Parasitic Drain, etc. Subaru's published tolerance is 70 mA; anything below is considered acceptable. A "normal" healthy modern Subaru will typically show around 30-35 mA draw.The Subaru maximum for dark current back in gen3 days was 150 ma, but as of 2010 or so, a new spec of ~70 ma was issued (although I think that might have been meant more for the later generation). The best bet might be to just get a battery disconnect switch.
