Hello Zhihao,

Lifetime data is written to flash only under specific conditions as described in the TRM. The values stored are as measured by the gauge when it is active(not in shutdown)

Hi Shirish,

I understand the values stored are as measured by the gauge when it is active, my question is what is the error between lifetime data and real life time when the gauge is active?

The error is the same as values of voltage, current and temperature accuracy specified in datasheet
