This was my 2nd replacement on this model MBP with IFixit kit. I didn’t remove any components. I covered display. I found that slipping the plastic card slightly under the battery until it hits adhesive and then let a few drops of solvent roll down the card to the adhesive/battery as you are working the card back and forth works really quick. The edge of the card puts the solvent right where it is needed. Was able remove battery in a few minutes without excess solvent or a mess.
