Oh boy am I going to start one big drama thread here (I am looking at you 12th Gen Intel Core BIOS 3.06 Beta !). Sorry for everything that is about to go wrong (or maybe not (but most likely yes…)).
The Framework Laptop 13 Battery is designed to be replaceable and upgradeable. Pick from 55Wh and higher-capacity 61Wh options. Both retain up to 80% capacity after 1,000 cycles of use. For 61Wh support, 11th Gen laptops should be updated to 3.19 or newer BIOS, while 12th Gen BIOS support is still pending.
So presumably 13th gen is supported OOTB. So I probably have my batteries mixed
