What is the maximum acceptable parasitic draw?
“Typically, the normal amount of parasitic draw is between 50 and 85 milliamps in newer cars and less than 50 milliamps for older cars.” A parasitic draw above this threshold is considered excessive. Over time, excessive drain can stress your battery, drawing it down quicker and shortening its life.Oct 10, 2022
Yes, I did take time to review the M38 TM (-8012 and the Army's trtaining manual TM 9-8000 Principles of Automotive Vehicles and found no answer in them.
