I just measured the charge current from a Z-car charger (funny pod thing) at 0.88amp /45 sec time, using energizer alkaline AAA's.
That will run my car for 4.5 mins with the yellow 2.2 motor on a tile floor. If I charge twice, I get about 7-8mins, and the car has more torque too.

From my calculations, each charge would give the batt 11maH
If my Z-car ran 4 mins on that, that would mean it was taking about 165mA to finish off that one charge in that 4 min run time.
(average current drain for the run, steering being used maybe 1/4 of the time, oval course, bumpy tile floor)

So if my 100mA batt was fully charged, and I ran it the same way (using 165maH driving/steering), It should, in theory, run for 36.3 mins.

My charger would have to give 9-45 second charges (6.81mins at 880mA) to reach the 100ma capacity-- Of course the batt would probably fry from such a high charge rate if done all in one session

Maybe some of this might help others figure out what their cars draw from their batts (I did all this calculating since I couldn't directly measure the car's current drain)

I think the RF receiver circuits must draw somehere around 10 mA, since one charge will take an hour or more to "fade away".
