BQ2060A Configuration

Other Parts Discussed in Thread: BQ2060, BQ2060A

I am looking for an example setup configuration for the BQ2060AEVM. I am using 6 C size NiMH cells in series. I tried setting up the configuration per the datasheet but it did not perform as expected. It recorded the charging of the cells up to 100% but when the charger was removed the charge level immediately dropped to less than 20%. EEPROM setup attached. Thanks.
