(b)(4).The reported complaint of "pump only ran on battery for 12 minutes" was not confirmed upon the investigation of the returned sample.The customer returned for investigation was a battery (part number: 4000-9022-001, lot number: 18f22l0006).The sample was returned in a brown cardboard box with protective packaging (inp-1, inp-2).Visual inspection of the battery was performed (inp-3 through inp-8) and no abnormality was noted.The battery was installed into a known good ac3 for functional testing.The iabp powered up successfully with no alarm, all voltages were present (+5v, +12v and -12v) and within specifications.The battery load test was performed.The iabp was run on battery until the iabp shut down.The battery was then left to charge in the iabp for over 9 hours.The full charge of battery was 12.9 volts (anp-2).The iabp gave a proper alarm when disconnected from the ac power (anp-3).Pumping was initiated (anp-4).The unit ran for over 90 minutes along with the proper alarms "less than 20-, 10-, and 5-minutes remaining" (anp-6 through anp-8).The operator manual states "the battery should be maintained at full charge whenever possible.Arrow international recommends that the ac3 iabp must be kept plugged into a proper ac receptacle whenever possible including time when the unit is in storage or not in use.The power indicator will illuminate when ac power is present.The batteries should not be stored in a discharged s tate." based on a review of the device history record (dhr), the product met specification upon release.The root cause of the complaint is undetermined.No further action required at this time.Teleflex will continue to monitor and trend on complaints of this nat ure.Other remarks: n/a.Corrected data: n/a.
