BQ34Z110: Failed Learning cycle on 12V 100AH Pb-Acid Battery

Hi,

I'm doing the learning cycle on BQ34Z110 with a 12V 100AH Lead-Acid battery and I'm referring to TI document SLUA903. 

My first question, is SLUA903 the right document for this IC? 

If No, can I refer to BQ34Z100-G1 TRM instead? Or can you share with me the correct documentation?

This is what I've done so far;

I manage to perform the learning cycle up until the first battery rest after full discharge (step 3.2.2 in SLUA903 ) but failed to get the correct flags and status which I assume the learning cycle is unsuccessful.

The steps I performed:

1. Configure the IC according to this thread until step 5. For other parameter, I leave it at default.
2. Perform Voltage and Current calibration.
3. Start the learning cycle with a fully charged battery.
4. Perform the learning cycle.
   
   1. Send Enable IT (0x21) then RESET (0x41). This set the [RUP_DIS] and [QEN] flags and changes the Update Status to 0x04.
   2. Then start discharge with a load of 3A.
   3. After the voltage reached around 10.8V, I stop the discharge and let the battery rest.
      1. I manage to get the [RUP_DIS] flag to clear and the [OCVTAKEN] flag to set. 
   4. Then, charge the battery to full at constant 3A.
      1. At this point the [VOK] flag is supposed to set automatically but it didn't. 
      2. Then [FC] is set at one point during the charging.
      3. But the update status remained 0x04 it should be 0x05.
   5. Now, I'm discharging the battery.

I would like to know, is 3A enough for the discharge and charge considering the battery capacity is 100AH?

Is the whole learning cycle unsuccesful because I refer to the wrong documentation?

Do I need the EV2400 hooked up to the IC at all time during the learning cycle?
