dear

BQ34110 battery meter chip is used to measure the battery power. The battery parameters are three ni-mh, the voltage parameters are 3.6v, and the capacity is 600mAh battery

Now use the EV2400+ EVM board to conduct some simple tests, and it is found that the battery capacity data read by the upper computer software is 2200mhA, and the CC offset calibration of the battery remains unchanged. any advice?upper computer show as below , thanks in advance

Hi Raymond,

Did you click the Read All button in the Data Memory Window after the CC offset calibration was done?

dear andy

It has clicked the Read All button in the Data Memory Window,but not work, read the value of the battery is still 2200mAh after used CCOFSET calibration and in fact to be tested battery parameters for 600mAh, show as below after starting up bqstudio

and connect the BQ34110 EVM board to the EV2400 device

The bq34110 evm board is connected to the battery to be tested. The red line is the positive electrode of the battery, and the black line is the negative electrode of the battery, which is connected to BAT+ and BAT- respectively

any advice?thanks in advance
