## Discrepancy

DURING A MAINTENANCE VISIT, THE EMERGENCY CABIN LIGHTS FROM BATTERY PACK M33400 WERE FOUND TO BE INOPERATIVE.  MAINTENANCE REMOVED THE CHARGER AND BATTERY PACKS M33400 AND M33405 AND INSTALLED CHARGER AND BATTERY SERIAL NUMBER 25185AT M33400 AND SERIAL NUMBER 589544 AT M33405.  SYSTEM OPERATION WAS NORMAL AFTER CHARGER AND BATTERY WERE REPLACED.
