Step 10

  • As you slice through the adhesive with the opening pick, try your best not to bend the battery pack. Soft shell lithium-ion batteries are highly susceptible to damage and can ignite when compromised.
  • Insert another opening pick into the right edge, near the first opening pick.
  • Slide the opening pick down along the right edge to loosen the right adhesive strip.
  • If the slicing feels difficult, apply a few more drops of isopropyl alcohol into the edge, wait a minute for it to seep in, and try again.
