I was doing a charge on my battery just to top it up. I think doing this helps bring each cell in the battery up to full charge. I think the charge on each cell would not be perfectly even with the others. Any way I disconnected the battery and measured the current from my charger and spent a few days tracking down the last load. What is important is the load at 12.5 volts which is normally where your battery sits during standby.
At 14.5 volts my radio clock and memory draws 1.77 ma. Radio is a Sony XR-C5100
My dome unit draws 0.88 ma. with a door open at 14.5 volts. note dome unit is shutdown in battery saver mode.
My door lock ECU draws 0.30 ma. at 14.5 volts
My alternator draws 0.41 ma. at 14.5 volts. note I have the DMCH unit with the sense connected to battery.
So my standby load was 3.38 ma. at 14.5 so will be a little less at 12.5 volts. Also less with all doors closed.
Now if you have a stock door lock unit add 12.5 ma.
A stock console clock I think adds another 5 ma.
I think the fanZilla took about 3 ma from my memory when I was testing that.
