that is correct
if your battery is draining from 27 mA then batt is not good
so are you 100% there is only a 27mA if so then batt is dead
I don't even know if you really know what you're talking about here.
I did a parasitic draw test on the car. The draw was 27 mA.
The battery is measured in volts not amps or milliamps so I don't even know what you're saying.
