I believe the problem is due to low idling speed and thic could be caused by dirty throttle body and IAC valve.
If the problem had occurred only after replacement of the battery, then the computer needs to relearn to stabiliser the idling speed.
Here is somethig that might help.
Start the engine with all load OFF.
Run until engine is at operating temperature and cooling fans comes on at least 2 times.
Turn A/C on and run for another 5 mins.
Test drive and see if problem is resolved.
