When battery #2 is nearly drained, I get a message that the computer has low power (it says 48%), then a few minutes later it shuts down. I turn it back on, check the battery status, says number #2 battery is 5%, says the other is around 60%. Five minutes later it shuts down again. Turn it back on, and it runs over a half hour before I shut the system down. Why is it not switching over to the nearly full battery? Where should I be looking to fix this?

If you recently upgraded to the 1803 version of Windows 10 that may be what caused it.
When you click microsoft battery icon on the task bar does it show both batteries?
If you look in Device Manager are both batteries listed?
The windows 10 - 1803 update screwed up a lot of Thinkpads with two batteries.
So, I can see no downside to trying this fix, it fixed my T480 with dual batteries:
I may have some extra unnecessary steps in here, but I wanted to be sure I didn't screw it up:
