Google didn't find much of interest.
Is there any resource of general tech info on laptop batteries?

Usually there's quite a bit of info in the app notes for the various
fuel gauge and controller chips.

This might be of interest:

Some I've opened have Arizona Microchip PIC on the PCB, some have BQ prefix
charge control chips - those I can maybe find online.

Just Microchip, not Az Microchip.
