Manufacturer Narrative
|
The reported complaint of "the autopulse li-ion battery (sn (b)(4)) does not hold charge and doesn't power up the autopulse platform" was confirmed during the functional testing and archive data review.The root cause for the failure was due to the damaged field effect transistor (fet) caused by electrostatic discharge (esd) exposure.Upon visual inspection, no physical damaged was observed and four green lights were lit on incoming inspection.The battery failed charging in a known good autopulse multi-chemistry battery charger (mcc).The battery was also tested in a known good autopulse platform and the battery failed to power up the platform.The battery archive data showed that the battery recorded a repeated cell over-voltage detected errors from start to the end of the archive followed by a multiple preserved mode with possible one or more battery cells discharged below 2.0 volts and clock glitch.The common cause of the repeated over-voltage was due to esd where the bleed-fet gets damaged causing the battery cells to leak and drain.
