Dear Expert
The BQ27542 power meter used in our previous project experienced abnormal RM (residual capacity, some even 1mAH) jump when the battery voltage was around 3.78V (normal) during the aging process in the production line aging cabinet according to the following steps.
Aging steps (GG file reference attachment):
1. At 25 ± 3 ℃, discharge at a constant current of 0.5C to 3.0V;
2. Let it sit for 10 minutes;
3. Charge at a constant current of 0.5C to 4.35V, and then maintain a constant voltage to 0.02C;
4. Let it sit for 10 minutes;
5. 0.5C constant current discharge to 3.0V;
6. Let it sit for 10 minutes;
7. Charge at a constant current of 0.2C to 3.79V, and then maintain a constant voltage of 0.02C;
