## Discrepancy

ELT FAILED OPS CHECK.  REMOVAL AND INSPECTION REVEALED 2 D CELL BATTERIES LEAKING PROFUSELY.  UNIT WAS CLEANED AND INSPECTED AND ALL CELLS WERE REPLACED, EXPIRATION DATES WERE 2017.  BATTERY EXPIRATION DATES WERE ALL 2019.  6 (SIX) MONTHS LATER THE ELT WAS AGAIN INSPECTED, THIS TIME, ALL 8 BATTERIES WERE LEAKING AND THE DEVICE HAD DAMAGE ON THE CIRCUIT BOARD AS WELL AS BATTERY CONTACTS.  DEVICE WAS REPLACED WITH A 406 MHZ UNIT FROM ANOTHER MANUFACTURER.  RECOMMEND FAA/MFR MODIFY ICA TO PERMIT BATTERIES AS IT APPEARS THAT BATTERY QUALITY HAS DANGEROUSLY DETERIORATED OVER THE PAST SEVERAL YEARS.
