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 at the top right corner of the battery where the flex cable is located and start to pry the battery up.

Work your way down the right side of the battery and loosen the adhesive with the spudger.
