How does the screen reattach? Do i need glue/tape? Does this come with adhesive to reattach screen? Or does the screen reattach to the old adhesive?

Thanks for your inquiry. After finishing installing the battery, you'd better intall adhesive on the notebook and then reattach the screen.

When was the battery manufactured? I don't see a manufacturing date on the battery.
