## Discrepancy

DURING FLIGHT, THE CREW NOTED THE BATTERY WAS NOT CHARGING SINCE THE BATTERY CHANGE LIGHT HAD STAYED ON SINCE START UP AND WAS STILL DRAWING 10-20 AMPS.  INSTEAD  STRANDING THE AC, THE DECISION WAS MADE TO PERFORMED AN AIR-TURN-BACK.  MX CHARGED THE BATTERY AND INSPECTED THE SYSTEM AND FOUND NO DISCREPANCIES.  MX REPLACED THE BATTERY AND RETURNED AC TO SERVICE WITH NO FURTHER DEFECTS. (K)
