Unfortunately, there's no simple way to answer this because there are too many variables:
- how healthy is the battery?
- what's the ambient temperature (battery performance declines significantly as temperature drops)
- what load are you putting on the battery?
- how long are you running this load?
Also, I see you have an automatic, so you face 2 additional challenges:
1) you have to use the starter (high amp draw) to reignite the engine;
2) you have no backup means of starting the car (clutch starting) should you draw the battery down so far that the starter won't work.
To be safe, you need to use a multimeter to experimentally figure out what you want to know, based on your specific circumstances.
Also, consider the point that from a financial perspective: you will almost certainly spend more money in battery replacement costs than you will get from fuel savings. Starting batteries are not meant to be charged/discharged any significant amount. Doing so shortens their lifespan.
Definitely caveat experimentor on this one!
