The battery is held to the device with two adhesive strips located on its underside.

After the battery is freed from the device, it will remain connected to the motherboard by two short wires.

Use the spudger tool to gently pry around both sides of the battery until it can be lifted from the device.

Roll the battery over (as shown in the image) so that its underside is now facing up. This will prevent damage to the motherboard.
