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 have the flat ones. Mainly using it for paperwork and running sdrtrunk. I'm happy either way but wanting to get new batteries eventually.

New batteries are not too expensive straight from a Panasonic retailer. Around 250 for the set. If you want to swap the back out you can fit the extended batteries you just can't put it on the keyboard backwards and close it anymore.

Use the Panasonic utility and check the battery health you might have some decent packs.

Even my bum batteries last longer then my brand new expensive dell precision by several times. Like its hilarious the difference.

I picked this unit up for $200 with no ssd. Had it running and charging in 20 minutes lol.
