Hello Everyone,

I have a question about fuel gauges, in particular bq2060a.  I am using a bq2060a interfacing with OMAP3 using HDQ interface.  After a few charge and discharge cycles I see a divergence in measured voltage vs. measured charge.  For example, I read 7.6 volts from fuel gauge while remaining capacity shows %1.  The new battery typically maps such voltage with around %30 of remaining capacity.  Is this normal?  What is the best way to make sense of fuel gauge?  It seems that the chip gets out of calibration and cannot converge to a proper value anymore.

Please let me know if you need more info.
