Either the battery is bad or the alternator isn't recharging the battery. You may want to have it checked by another person. NOTE: If the alt is checking good and the battery still checks good, there could be a wiring issue between the alt and the battery or since you hear a chirping noise from the belt when the alt is loaded, the belt may just be slipping.
Check these things and let me know what you find.
