Try your best not to deform the battery during the following removal process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.

Insert the flat end of a spudger under the bottom left corner of the battery and gently pry upwards.

The adhesive is only located beneath the edges of the battery so there's no need to pry beneath its center.

If you are having trouble prying up the battery, the adhesive may not be loose enough. You can apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.
