As reported, during the training, a fully charged autopulse li-ion battery (sn (b)(4)) was removed from the multi-chemistry charger (mcc) and placed into the autopulse platform.However, the battery failed to power up the platform.The battery was placed back for charging and was disabled by the charger.No patient involvement.

The battery failed to charge in a known good multi-chemistry charger.The battery was tested in a known good autopulse platform and failed to power up, confirming the customer complaint.No physical damage was observed and three amber lights were lit on incoming inspection.The battery archive was downloaded and reviewed.The cause for this battery failure, based on the review of the battery, is due to battery mismanagement and charging practice by the customer.The battery was left multiple times in the autopulse platform for an extended period of time and let it deplete below operating voltage.As a result of these errors, the battery failed to charge in the multi-chemistry charger and failed to power up the autopulse platform.The autopulse power system user guide states that "after every use, at the beginning of a shift, or at least once every 24 hours, the battery in the autopulse should be replaced with a fully charged battery." a fully charged autopulse lithium-ion battery left in a zoll autopulse platform for an extended period of time will eventually discharge below its minimum operating voltage.A fully discharged battery will not be able to charge in the mcc.
