A B737-300 WAS DISPATCHED IN NON COMPLIANCE WITH THE EMER EXIT DOOR LIGHTING SYS INOP DUE TO DEAD BATTERIES.

Narrative

ON THE NIGHT OF AUG/XA/00 AT APPROX XA00; I OBSERVED ACR B737-300 XYZ PUSH BACK TO ITS OVERNIGHT PARKING SPOT NEXT TO GATE AB AT THE ZZZ ARPT. AT THAT TIME I NOTICED THAT THE EXTERIOR EMER EXIT LIGHTS WERE ON WITH ACFT PWR OFF. SEVERAL MINS LATER AFTER EXITING THE ACFT I WAS WORKING ON; I SAW THAT THE LIGHTS WERE STILL ON; BUT THAT SOMEONE WAS IN THE COCKPIT WITH A FLASHLIGHT. LATER STILL; AS I WAS AT THE REAR OF MY ACFT; I NOTICED THAT ALL BUT 1 OF THE LIGHTS ON THE R SIDE OF ACFT XYZ WERE OFF; AND LATER IT TOO WAS OFF. THE FOLLOWING MORNING (AUG/XA/00) AT APPROX XG15; I RPTED TO ACR SUPVR (VX WXX) WHAT HAD HAPPENED AND SUGGESTED THAT AN FBO MECH BE CALLED TO CHK THE SYS FOR PROPER OP. HE TOLD ME THAT HE WOULD RPT IT TO THE ACFT CAPT; AND I AGAIN SUGGESTED THAT AN A&P MECH BE CALLED. AT THAT POINT I RETURNED TO MY WORK AREA. AT ABOUT XH15 I RETURNED TO THE ACR OFFICE AND INQUIRED ABOUT THE ACFT AND WAS TOLD THAT THE CAPT WAS INFORMED AND TOLD THE SUPVR (VX WXX) THAT THE BATTERIES WOULD RECHARGE WITH SHIP'S PWR. KNOWING THAT ON ACR X ACFT THE EXIT LIGHT BATTERIES TAKE ABOUT 16 HRS TO RECHARGE; I FELT THAT THE ACFT WAS DISPATCHED WITH A KNOWN PROB AND THAT A RPT SHOULD BE FILED TO COVER MYSELF IF FURTHER PROBS CAME ABOUT BECAUSE OF THIS INCIDENT.
