Will driving my car fully recharge my battery?

Some factors affecting a car charging system's ability to charge are;

1. How much current from the alternator is diverted to the battery to charge it
2. How long the current is available, and at what temperature the charging activity is taking place.

Generally, idling the engine or on short “stop-and-go trips” during cold or hot weather or at night will not recharge a battery. A long daytime trip in warm weather should recharge a battery.
