Tool/software:
our customer found few batteries which use BQ27742-G1 work abnormally ,now we received one of them, the communication information on the right side picture that shown us SOH only remaining 33%,
Look into the data flash, we found that the Ra-table change abnormally and also , the unseal key and authentication key both been clean to 0 ,we confirm with customer that the terminal don't have the unseal key ,
in this way the terminal have no way to unseal the fuel gauge and change the value in the register, to sum up, we suppose the data in the Gauge was updating abnormally by itself, does it have any condition will cause the similar failure?
