Have them check the alternator. Also, make sure the ground to the engine block is tight and clean. Finally, if the battery isn't recharging properly, have them check the fuseable link between the alt and the battery as well as all electrical connections on the rear of the alt. NOTE: When the alt is checked (most part stores do it for free) make sure they also check the voltage regulator.
