TechSupport Battery question

I just got a great condition cf33 and was wondering, do the batteries discharge one at a time and have 8ish hours a piece or total? Its saying battery 2 in use and battery 1 is fully charged.

I just got a cf33 recently too, batteries discharge 1 at a time

And 8 hours total or 4h each.

The extended packs are 10h each 20h total or there abouts

I'm running Win 11 on mine and I think the way the battery percent makes sense but its weird. (One battery will be at 15% and the other at 100% but the laptop will say like 30% battery left)
