From my experience, no this is not at all normal.

All of my 1900 mAh LSD AA battery 4-pack kits when new were only about 67% full, give or take 1% or 2% and they all had initial no load voltages ~ 1.32 volts.

When charging four AA batteries, the BQ-CC55 uses a 750 mA charge rate.

The BQ-CC17

**always** uses a 300 mA charge rate for AA batteries all of the time, whether you're charging one, two, three or four batteries. This means that if all eight batteries have similar initial precharged capacity, the BQ-CC55 batteries should finish much sooner.

If all of your batteries are 2/3 full before charging, this means that there is 1900 mAh minus 1273 mAh equals 627 mAh of unavailable capacity.

Here's a ballpark formula: total capacity divided by the charging rate = how long it will take (in hours) to fully charge a depleted battery.

In your case 627 mAh divided by 750 mA = 0.836 hour or approximately

**50 minutes** for the BQ-CC55 to finishing charging 3 or 4 AA batteries.

627 mAh divided by 300 mA = 2.09 hours or about

**125 minutes** for the BQ-CC17 to finishing charging one or more batteries.

Keep in mind that it takes several charge/discharge cycles for new batteries to be fully broken in where they should easily meet their rated specs.

I don't have an explanation why your results are bass ackwards, maybe you have a half-fast BQ-CC55.
