This article suggests a 50mA typical:
Inside Look at Charging System Quote:"There is no one acceptable specification for parasitic draw because it varies from manufacturer to manufacturer and from model year to model year; but they all agree that the lower the draw the better. Some newer vehicles can draw up to 75mA with the ignition off and still be within acceptable limits. While some manufacturers, such as Dodge, claim that no more than 20mA is acceptable on some modelsthe Dodge Dakota, for example. A general guideline to follow is to allow no more than 50mA draw with the ignition off. A battery with 50mA draw will usually last in a vehicle for approximately 20-30 days without the vehicle being driven" (End of Quote)
