Questions about this item
Does the GreenTech B31N1912 C31N1912 42WHR battery come with installation tools or must they be bought separately?

All four numbers refer to the same 11.55 V, 3640 mAh, 3-cell pack; match any one of them to the label on your original battery to confirm fit.
What does the 42 Wh rating mean for real-world runtime in a VivoBook 14 E410MA?
