Is it normal for a battery to draw 85 milliamp?
However, just because an 85-milliamp draw may be normal, that doesn’t mean an 85-milliamp draw won’t adversely impact battery lifespan and performance, if the battery isn’t properly-maintained.
What’s the normal parasitic draw on a car battery?
On newer cars the parasitic draw is slightly higher than on older cars due to the increase of electronic systems. A normal parasitic draw is about 50mA or 0.05 amps, but the range can be anywhere from about 0.03 to 0.085 amps (30-85mA).
