The driver's alarm history was reviewed and no alarms were found recorded in the driver's eeprom.Only permanent alarms, alarms lasting more than 4 minutes and 15 seconds, are recorded in the eeprom.Intermittent and/or recoverable alarms would not be recorded.Visual inspection of the driver revealed a small piece of metal wire inside the right battery well.Functional testing was not performed with the wire in the battery well because of the risk of a short that could potentially damage the driver or onboard batteries.An onboard battery exchange test was performed using nine onboard batteries that have previously passed syncardia's acceptance criteria.No alarms were produced during this test.During investigation testing, the customer-reported issue could not be confirmed.Because of the potential risk of damage to the driver and onboard batteries, it could not be conclusively determined if the foreign object found in the right battery well was the root cause of the customer-reported alarm during an onboard battery exchanged.This issue will continue to be monitored and trended as part of the customer experience process.Syncardia has completed its evaluation of this complaint and is closing this file.(b)(4) follow-up report 1.
