The reported complaint was confirmed during functional testing of the returned autopulse lithium-ion battery.The battery failed to charge in a known good multi-chemistry charger.Dents on the battery case were observed, and four green lights were lit on incoming inspection.From the battery archive review, on june 4, 2018, to the end of the archive on july 11, 2018, battery recorded multiple temperature mismatch error messages during each customer's autopulse used/insertions and charged attempts.The battery was last charged successfully on (b)(6) 2018, and was last inserted/used in the autopulse by the customer the same day.The cause for this battery failure, based on the review of the battery, is due to a mechanical impact resulting in a damage of one of the battery temperature sensors.As a result, the battery could not be charged and failed in the autopulse platform.
