Repeat the previous two steps to remove the three adhesive strips on the other side of the battery.

If any of the adhesive strips broke, you can use high-concentration (>90%) isopropyl alcohol to help remove them:

Carefully drip isopropyl alcohol along either edge of the battery, in the recessed part of the upper case, where the adhesive pull tabs were.

Applying too much alcohol or applying it outside of the wells in the case where the adhesive sits risks damaging other components.

Let the alcohol soak into the adhesive for a minute or two.

Use opening picks to gently pry the battery away from the upper case.
