Google didn't find much of interest.

Is there any resource of general tech info on laptop batteries?

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

Thanks for any help.

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:

Just Microchip, not Az Microchip.

Last time I used the term; "microchip" - everyone assumed I meant just a
chip.
