COMPLIED WITH TASK CARD TC-FLT-33-1001 BY ALLOWING THE EMERGENCY LIGHT BATTERIES TO CHARGE FOR 60 MINUTES. PERFORMED DISCHARGE OF THE EMERGENCY LIGHT POWER SUPPLY BATTERIES, ALL LIGHTS REMAIN ILLUMINATED LONGER THAN 10 MINUTES. PER TASK CARD TC·FLT-33-1001 THE BATTERIES ARE AIRWORTHY. RE- CHARGED FOR 60 MINUTES, CALLED MCC OF FINDING AND THEY ELECT TO SIGN OFF ALL WORK WAS DONE AS PER AMM 33-50-00.
