The Intel® RAID Smart Battery AXXRSBBU4 is an optional accessory for the Intel® RAID Controllers SRCSASRB and SRCSATAWB.
Intel has found that some AXXRSBBU4 units with specific date codes may experience an issue with a damaged thermistor. The thermistor damage results in extreme battery temperature values being reported that are outside of the operable temperature window. This temperature results in triggering the BBU overheating protection mechanism and prevents the battery from charging.
