What's a typical drain on a battery while connected to a car?

When you got .50 amps, who long had it been since they had been on?

I don't recall the actual timing but it takes a while for the ecm to go to sleep mode.

The car had been sitting less than 24 hr since I last ran it, when I made the measurement.
