A capacitor on the pcb of the battery charger was noted to be burned, this is likely due to the ingress of a fluid.The residue left by the fluid was identified by chemical composition testing to contain sodium chloride.The residue on the pcb was located under both battery wells.In addition, the shape of the residue matched the shape of the battery wells themselves.Based on the location and the shape, it is likely that the sodium chloride solution entered the charger through the battery well of the charger, after assembly.The manufacturing processes were reviewed and sodium chloride is not used during the manufacturing of the battery charger.In addition, the customer indicated they did not use a sodium chloride solution on the battery charger at any time.Therefore, the source of the sodium chloride fluid residue could not be confirmed.Review of the complaint history for this device determined that the reported event is an isolated incident.No other reports of smoking have been received for battery chargers used in conjunction with the bladderscan prime.Corrective action is not required at this time.Verathon will continue to monitor for trends.
