Laptop battery tech info.
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.
