received battery with discharged cells and locked. after reset, tried to calibrate. discharging stops at 52% as one cell reaches 2900mv. big deviation shows cells are poor but cells check shows resistance around 90mOhm. instead of decreasing, FCC increased.
reset the chip and tried again. same happened and FCC calculated wrong than measured capacity.
why this is happening and what is solution?
Max Error is 110% so relearning cycles were not completed properly.
If calibration cycles were successful max error value will be close to 1%
Follow TI recommendations for IT gauges relaxations periods, 2 hours after charge and 5 hours after discharge.
Also check average laptop power consumption and adjust the discharge current in NLBA according to it.
ALso 2900mv stop condition is just a little bit too low, set it 3000mv just to make sure chip will not discard the learning cycle because of this.
