Per the fsr, further investigation of the data logs showed the system-1 has not been powered on since his last inspection on 08/18/2014.The batteries are both below 5.0 volts direct current (vdc) unloaded.The fsr installed new batteries, copied all data logs, and completed a full inspection.The unit operated to manufacturer specs and was returned to clinical use.The fsr talked with the perfusionist (ccp) and she was aware of the charging requirements, but forgot to tend to this backup system.The ccp will now swap systems on a regular basis or start a charging schedule on this system.The suspect batteries were returned to the mfr for further eval.The reported complaint was corroborated during the laboratory eval.The batteries were received in a severely depleted condition.After charging for 28 hours, the batteries both properly accepted charging and held up under load for the required time.The discharge test exceeded the required 50 minute load test by 15 minutes.Both batteries exceed minimum requirements for conductance and discharge tests.The data logs confirm that the system was left unplugged from power without recharging for an extended period of time.
