The automatic idle speed control system has lost its adaptive idle learning due to the dead battery. To help to correct this in the short term run the engine at 2000 RPM until warm, then back down to 1500 RPM for 3 minutes, then 1000 RPM for 3 minutes, then let it idle for 5 minutes, this should get the system to a point in the idle learn that it doesn't stall out, then drive it for 20 miles under varied conditions of highway and stop and go and low speed operation, that should get all to work again. If you still have problems you will need to have the system scanned to see what is going on that is causing a stall. Also add fresh fuel, gas goes bad in about 3 months. Use the recommended grade of fuel.

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
