Jack,
I have never sat down and measured the power consumption of a Scalextric car, but I do know that the stock Scalextric Wallwort is 14.8 volts at 200 milliamps.
A typical auto battery, when fully charged will provide 13.2 volts and depending on the size of the battery, can supply up to 480 amp hours.
You can safely run several Scalextric cars around all day long with that battery. Just make sure it is fully charged prior to using it and then charge it back up after the event.
I hope this helps.
Marty
