Default Battery drain

Hi rob, just recognized your handle. My multi volt portion of my meter is not working. However with the meter in series between the cable and terminal set on dc miliamps i am reading 0.17
milliamps. I've read where that would b considered a normal draw. Is that so ?
thanks in advance

17 mA is fine if this is for me….normal drain is roughly the Reserve Capacity (RC) in minutes of your battery divided by 4.

Not sure if it means anything but on my volt meter that same connection shows full voltage
Forgot to mention that the battery had been fully charged and disconnected for a few hours reading .17 mA

Where are you reading this “full voltage”…at the battery??…fully charged battery is 12.66 volts…you normally check for this drain after all the modules “go to sleep” which is roughly 20-30 minutes after closing all the doors, locking the car and walking away.

Are you reading .017 or 0.17??

.017 = 17 milliamps
0.17 = 170 milliamps

170 would be a lot.
