| NOTE: The mainboard will charge this battery, so a rechargable ML1220 battery must be used. | ||
| CR2032 is not okay because it cannot be charged. |

you will get explody batteries if you do that, maybe we should include some warnings after a little more research.

| Framework 13 Intel Core 11th through 13th Generation use an onboard coin cell battery as RTC. | ||
| These systems ship with a battery that keeps BIOS time, settings and configuration. |

Might be useful to say ram training data is stored here, so if you don't have a battery the board will take forever to boot, not just the first time but every time.

The pin numbers might not be obvious, how about we hint at left vs right with a drawing, or some kind of tip to look (or probe) for the ground plane.
I literally had to check the gerber layout and double check it with a multimeter to be sure when i had to hack a battery on.
