Gently wedge the spudger under the battery starting from the left side, and slowly work the spudger around the edge to loosen the battery from the tape. Be careful not to rip the thin foil on the back of the battery.

Only use ESD safe tools when working on internal components of your device such as a spudger or opening tool.

It is not advised to use a metal spudger, as you could puncture the battery.
