The stock alternators on these cars are relatively weak, and will not support a full electrical load at idle without draining some charge from the battery. However, that is not a normal operating condition. Under normal operating conditions (car movement) the stock alternator will keep the battery charged.
Sounds to me like you have a normal charge situation.
