Optimization Cycle bq34z100-G1

Hello everyone,

I am trying to run an otimization cycle in my Lead Acid 12V 18Ah battery using the bq34z100-G1, but with no sucess.

My first step was to set all the configuration parameters and gage parameters according to the battery manufacturer, such as Term Voltage (10,5V), Qmax (18000mAh)...

Then, using GPC, I found the best chem ID (808).

I thought I would be alright to start the optimization cycle, following the slua334b document  - "When a close Qmax value is known".

But, after discharging the battery, Max error still in 100%.

Am I doing something wrong?

Thanks in advance!
