I followed Alana's advice (comment from Jan 11, 2024. Definitely fragile, also definitely do-able as someone who has never done something like this before. They don't need to be dramatically raised, just make sure they are raised enough that the tip can reach far enough that it will touch the battery when it's sitting on the sticky padding. For mine, I gave it some gentle leverage from the base of the pin until I could see the tip above the sticky pad when looking at it from the side. It seems to have worked, as the earbuds are working correctly after reassembly.

@alana48457 thank you for the help with re-assembly. I almost took the sticky stuff and threw it away, glad I read your comment first!
