This guide will walk you through the steps to replacing the internal laptop battery of your Lenovo ThinkPad T480.

"What you need" contains a wrong part.
Hi @cumledomla, I've added the internal battery for this guide. Thanks for pointing that out! The external battery will show up in the "What you need" section because it's imported from the prerequisite guide for the external battery. Hope this helps.
The "Battery 2" on my T480 does not load. Is Battery 2 the internal or the external battery?
Battery 2 is the external battery.
